Our Reviews

I was contacted by Eli Lopez after I expressed interest in 2 GMC Sierras that were on the website. I made an appointment with Eli and a deal was struck on a Sierra Denali. Everything went smoothly and all communication was straightforward. David in the Finance Dept was easy to work with and the experience was smooth.

They did a great job and fixed everything.

everything fine except they left cap off my oil, i noticed my hood was about 1" up and popped hood and luckily they slammed it on the cap so cap was still there.

Transmission went out. Robert was amazing as usual. In and out quickly

Service was fast. Comfortable atmosphere.

Totally satisfied with the service I received at Mark Miller GMC. They did a great job fixing the repairs, were very helpful and kind. ( If I had a complaint it would be gettint someone to answer phone calls in the departments).

I made an appointment to have my oil changed and it still took over an hour and a half to complete the process.

It was very pleasant and efficient.

They explained everything I needed to know about my car.

Na

Work completed as needed

Nice to not be subjected to upselling

Started truck buying process online with Jorge and quickly led to a deal. Financing allowed me to do a sign and drive promissory note (which was nice) and once financing was complete with my bank, drove to dealership, paid up and that was that. Just an overall pleasant and easy process.

Everyone was very nice and welcoming. Lane was out sales rep, he was very knowledgeable and not Pushy at all

For 9 years I have had oil changes done at the dealership every 3k miles without fail because I have the Engine guarantee. When I began to have timing chain issue, I was advised by Robert Murray that my guarantee was void because for the last 3 changes something was not added. When I asked who was responsible for that he stated the the technician and I the customer were at fault. He said the tech should have added it and I should have made sure it was on the receipt. I have never in the 9yrs of owning this vehicle, been told that I was responsible for making sure the technician did there job. This is the worst example of customer service I have ever received. This is the 3rd vehicle I have purchased from Marc Miller and it will be the last. Robert Murray's audacity to blame the customer is disgusting.

From email reminder with info from on star to setting up the appointment was smooth thru the service work and checking out and paying

I appreciate the call I received to tell me the recall part was in and my appointment was scheduled the very next day. The work took only about an hour.

Everyone was courteous and professional. Everything I had done took a couple hours more than expected. I came in for an oil change, the service tech asked if I wanted to do a coolant and brake flush without telling me the price. I agreed thinking it would be in the $100-$200 range. The final bill was $950!!! WAY more than I was expecting to pay. When I asked her about it she just said “sorry” and walked off. You should really tell customers the price upfront!

Oil change. As always fast and professional. Always a shout out to Robert in service. He goes above and beyound.

Friend about specials you had going on. Filled out credit application and was contacted by salesman Jorge Hernandez. Once credit application was approved every thing fell into place perfectly. Jorge was extremely helpful. Jorge answered all our questions and got us into a new encore. Look forward to calling Jorge for our next vehicle

Friendly, honest, thorough, and detailed. The work was completed quickly and the communication was excellent.

fast, professional and friendly service each and every time!

Lane did a great job and was able to answer all my question. We were so happy with the service and the car.

Arrived on my appointment time didn't get out of there till 2 hours later which just an oil change and really have a good experience especially with my advisor being the first time being there I don't think I want to come back to that dealership

Everyone at the dealership was very courteous, knowledgeable, and professional in this transaction. I am completely satisfied with my recent experience at Marc Miller Buick~GMC.

The team was great, they helped me out with everything and was an overall great experience.

We were pleased with the service and information we received from Angel Hernandez, your New Car Salesman. Your finance department made everything simple to understand and quick to address all matters. I am looking forward to your service department continuing the excellent service in the future.

Robert is always great to work with; knowledgeable and responsive.

My appointment went great. In a little over an hour, the work was completed including a detailed explanation. Great job!!!!

Always helpful and courteous

FAST FRIENDLY SERVICE

Quick

The service team did a great job with my wife's Yukon! She is very happy with her new breaks! We will refer all my friends and family!

Our sales consultant was extremely helpful and a delight to work with! He demonstrated trust immediately and was anxious to make sure we were satisfied! We would work with Mike again in a heartbeat and encourage others to seek him out as well! The finance side was amazing too! NO hidden fees or add-on charges. What a relief to not be hit with that as we were signing papers! Well done!

Service at the dealership keeps my car running smoothly. The employees are courteous and take time to explain what my car needs.

Robert is the service department was very helpful and courteous.

It would be nice if someone would guide you into the service area. There were people grouped talking while I was in front of the bay doors. I didn’t know if I’m supposed to pull in or wait. Also, it took 2 hours for an oil change, tire rotation and filter change. It normally takes an hour so this was a little ridiculous. I went and asked how much longer and guess what, “looks like they just finished”. Then it took 30 more minutes before I actually left. You guys are across the street from my office but I’m not sure I’ll be back. I use Ferguson for my wife’s car and feel they are way ahead.

The staff at Marc Miller were courteous and efficient.

Great service

Excellent service

For the second time- the "computer" wouldn't allow them to use my points so I had to pay full price- why do I even have these stupid points if I can't use them. I'm not going back ever again- also, it takes FOREVER even when you have a scheduled appointment.

I was amazed at the ability of everyone

The dealership staff was very patient and professional

I always receive great, friendly service. They do an excellent job detailing my car also.

I appreciate their quick service.

Ready as promised

Huge thanks to Andrew & his very capable service team -- we might've finally solved the phantom computer shutdowns that've been haunting us during important travels coast to coast, involving expensive, majorly interruptive towing events to different dealerships!

Quick service and nice people

Robert Murray always takes AMAZING care when we need service for our cars!

When I got there I went to the oil change instead of the body shop because that's where I'm used to going. I will never make that mistake again. When I told the gentleman what I needed he told me to go over there he started to walk off and I told him I had a few questions. I begin to ask questions and he wasn't having it he told me to just go over there (Not a nice person). I don't know his name but I know his face and I will never deal with him again.

My experience buying a 2025 Buick Envision from Marc Miller Buick was amazing. Jorge was the best salesman; he didn't push, was willing to work with me, & completed the process in a very timely manner. Everyone at the dealership was respectful and willing to help in any way they could. Will highly recommend Marc Miller to anyone looking for a GM vehicle.

Appointment was very easy to schedule online. They were ready when I arrived. Staff was friendly.

No complaints from me!

The waiting room was dirty. People were more concerned with their break times instead of focusing on the customers. I brought our Buick in for its first oil change, took longer than anticipated.

My only complaint is I was told, when I bought the new truck, that if I ever needed service, I would get a loaner car. I was told no loaners were available and they only had a very limited number of loaners. This meant I had to miss a day of work because I had nothing to drive.

Dropped off my GMC for an oil change, work was done in very reasonable time.

April was amazing! She was very kind to my daughter and me. My daughter is very curious and talkative, and she answered her questions and laughed with her. She will be the reason I will keep coming back

I was in and out in 20 minutes for an oil change and tire rotation.

Great atmosphere and fast, friendly service.

First oil change. All went well but didn’t get to talk to anyone in service with a couple of questions My salesman was on vc but will go back later and talk with them. All good!!!

Lance was very knowledgeable and low key. He allowed me to shop at my pace with no pressure and was available for questions with a well thought out and understandable answers. He knew his product and was very approachable and patient.

Great communication by service department.

Great service

Took two days but the work was done on the engine recall. I hope it fixed the problem with the crankshaft and bearings with just a change of oil viscosity.

It's important to have a service writer available when departing to make sure there is nothing more needed from the customer. Also have the seat and floor protectors removed prior to customers getting in the vehicle.

The vacuum job was only a quarter done. They didn't do the driver side at all they didn't do any of the seats. Didn't do any if the backseats at all. Just a very poor job.

Lane did a fantastic job, helping me find and purchase my new GMC. I likely would not have found the 2025 model, with the exact options that I wanted, had it not been for Lane. I purchased my new truck from Lane over the phone, sight unseen. However his straightforward professionalism, gave me much confidence in the deal. Everything went smoothly and as expected, when I took delivery. In the time that I had for the vehicle orientation, Lane was very knowledgeable of all the features and operations and explained them in detail that was easily understandable. I departed as I planned and had great 300 mile drive to my destination. I once again want to thank Lane and everyone at Mark Miller GMC, who made this one of my best vehicle purchases ! Randy McKee

Great Job very fast

I was able to bring my vehicle in right after lunch and get it back the same day even though several services were performed.

I brought in my Yukon to repair a tire sensor. I did not have an appointment. You made the repair in a little over an hour. Thanks Great service

Great experience and I love my new car

Always helpful

I really appreciate a clean car, however I have been very displeased with your service department upon returning my vehicle after service. My last two visits 2024 GMC Terrain and my 2025 Buick Envision both returned with greasy fingerprints on the hood after an oil changed. Please ask your technician to take pride in customer's vehicles. Thank you

Very good to work with

Everything went fast and efficient.

Robert and his team always take care of me. They let me know what needs to be done to keep my car safe and running smoothly. I drive a lot of miles and my car is my friend !!! :-) And so are Robert and his team !!!!!

We love shopping for our vehicles at Marc Miller. Everyone is always very helpful. We have worked with Mike Harwell, Steve and Eric several vehicle purchases and have always had the best customer service.

I had an excellent experience. The staff was very accommodating. In all my years of buying a car, this was by far the fastest and most efficient process I have experienced.

Like the text & email responses when car ready.

We were shopping all around town trying to find the best price, looking at different makes, dealerships, etc. At Marc Miller Buick-GMC, we found the most honest salesman in George and the best deal. All straightforward, making it one of our easiest vehicle purchases in over 25 years... that says a lot.

Employees were courteous, prompt and completed the work right. And above honesty. We appreciate good service.

In and out

I always have helpful and friendly service at their service station. Their team actually cares about their customers as people, not just a pay check.

It was quick, excellent customer service.

Sales person (Lane) was very helpful for both myself and my wife during the process. Everyone answered all questions, and helped us get the deal done

Quick and friendly

Would give a 6th Star if I could. Went beyond for me on my New Envision

Destiny went far and beyond customer service. I truly appreciate her assistance in helping me get my rewards reimbursement. I am very disappointed in the rewards department, which I did express to them via email, which took an hour and a half. This includes the rewards department disconnecting the call after Destiny was placed on hold. Also, Advisor, Andrew Browning was concerned and patient with me. I appreciated this.

Mike did an excellent job working with me to get the truck I wanted. The experience was easy and I would recommend the dealership to my friends and family.

I came in for a new set of tires for my 2020 GMC Sierra. They installed my new tires on someone else's vehicle. After I paid for my job they tried to give me the keys to the other person's vehicle as well. After I pointed out this information it was corrected but not until I had already been waiting at the dealership for over three and a half hours. Hopefully they did the alignment that I paid for. I also had and oil change done a few weeks earlier and they left the oil cap in the space between my window and the hood. I didn't notice it for a few days. Thank goodness it hadn't slid off before I noticed it.

they found the problem quickly and fixed

did a good job

Service department didn't hold up to the anticipation on a routine vehicle check 🙄

You were able to diagnose and repair the problems in short order.

What I exected from a good dealership

Pretty quick

From drop off to being done, I had an oil change in around 30 minutes. Great job guys!!

Great service and we didn’t have an appointment.

They honored the appointment time and were able to complete the oil change, tire rotation, and inspection in under 45 minutes. The only negative point is I did not receive a hard copy of the inspection, and the digital version had zero check marks or comments (tire tread depth, fluids, etc).

Outside of the fact that it took TWO days for my car to be finished when it was supposed to be done, because someone in your department broke a hose, and the fact that it was then discovered that the radiator had a split in it, which in turn caused the cost to go from $1300 to $1800.....everything went well.

I have bought several Buicks from the Marc Miller dealership, and Mike Harwell has been the person who helped make it an easy and pleasant experience.

I took my vehicle to service for a grinding noise in the front. They did great and had good communication. My only complaint was they asked if I wanted a complimentary car wash. Normally I say no because I detail it myself but, I went against my better judgement and had them do it. Now I’ve got scratches in my clearcoat. It’s on me though, I know better.

Was ready for my appointment at 7:00 a.m. had me back on road in a little over an hour

Always fast, friendly service.

Thanks for the quick Oil change. Even though they were short personal at service check-in the two left hustled the best...

My salesman Lane was exceptional. He worked with me and got the Denali we wanted. He made sure it had all the options we wanted and got it dealer traded. He also took care of all the window tint and paint protection film so it was ready before we bought the car. Very happy with the service.

Jorge was great, Great Service

Great buying experience!

Very informative and helpful.

The service was excellent, both scheduling a time for service and the process. The service dept was also able to replace a missing part on my vehicle which I was also thankful for. Oil change and a repair done in an hour or so, good service and work!

Got a good deal on tires for my truck.

Great experience! Our salesman did great! Smooth process.

I brought my vehicle in for a reoccurring issue where the check engine light is staying on. I was charged for diagnostic work, yet they could not replicate or fix the issue. This is not the first time I've been charged for diagnostic work where the issue was never resolved.

Lane Gaddy was excellent...start to finish

The process was so easy from start to finish and we love our new Acadia!

Mike was absolutely the most professional and kind salesman. From beginning to end. He did not push or hassle. He was eager to accommodate and get us the best deal and exactly what we wanted. Miranda in the business office was also very professional, quick and efficient. Overall the best car buying experience I've ever had in years of purchasing vehicles at dealerships. I highly recommend!!!

I very much appreciated the customer service April provided. This was my first experience with April. I told her that I needed her as my Service Advisor going forward. She was patient and persistent in working with the warranty company. Her communication with me was excellent.

Fast and complete l

Robert Murray , the Service Rep. was professional, knowledgeable and friendly. The work was completed quickly and professionally.

Quick, good honest service

I had a 11:30 appointment and I arrived 11:00. Service advisor took the car and he came back at 11:25 and asked if I would my car washed. So what do you think, was I a happy camper.

When I arrived for the scheduled appointment, the service began immediately and was accomplished expeditiously. The service representative was personable, knowledgeable and took the time to fully explain the service recommended and the cost. Upon completion, I was provided documentation as to the work completed, the additional inspections made and future service that may be required. The car wash was also appreciated.

Thanks for the repair of my truck… very quick considering the labor… may need to trade soon… need a 2026 SLT soon…

Oil change and tire rotation. In out in 30 minutes. Thanks Tom

I was able to call and arrange an appointment for my 2025 GMC pickup. All went well and I used my free oil, oil filter from GM

Robert Murray is awesome

Customer service really felt lacking this time. Communication is poor. I felt I needed to call for any updates because I did not receive a phone call when told I would. When I picked my car up, no one told me what was done or what the problem had been. I asked the girl at the payment counter, and she obviously didn’t know. She told me my car was outside ready for me. It wasn’t. I had to find someone to go get it. It wasn’t washed. When he brought my car, he offered to wash it, but I didn’t have time to wait. I have dealt with other dealerships in the past, and sadly, the customer service here just does not compare.

Always a honest fair deal

Oil change completed timely.

We had a great experience at Marc Miller Buick GMC . Steve L. , Jorge & David took very good care of us , we expressed what we were needing & looking for & they met all of our expectations. It was by far our best Car buying experience.!! I would highly recommend Marc Miller Buick GMC !

Professional

Everything was done in a very fast time.

They contacted my extended warranty company and work with them to get my truck fixed.

Quick and easy, the service representative Robert Murray took care of my needs in a professional manner

Detailed, and good service

Always a good experience at Marc Miller

Service was fast and reasonably priced.

Service advisors were kind and my service was quick.

I was greeted immediately upon arriving at Marc Allen Buick-GMC, and the entire experience only got better from there. Steve (manager), Lane (sales), and Miranda (finance) truly went above and beyond to make me feel like a valued customer from start to finish—and even after the purchase. This was the smoothest and fastest vehicle-buying experience I’ve had since purchasing my first car in 2000. I’ve bought many vehicles over the years, but I’ve never experienced this level of professionalism, transparency, and seamless service. The entire team at Marc Allen Buick-GMC clearly values their customers and worked hard to get me into a vehicle I’ll enjoy for years to come at a great price. Highly recommend.

It was quick and reasonably priced.

Robert is a great service advisor

Excellent service, courteous

Great employees who always do a great job, I tell everyone to go there.

Great service.

Took truck in for a scheduled appointment at 12:30 for an oil change and was told it would be done in 45 minutes to an hour. I checked back at 2:00 and was told just a few more minutes which turned into another hour and a half. Didn’t get out of there until about 3:30. I’m not good at math but I believe that’s 3 hours for a simple oil change that was actually scheduled.

Car repaired as promised in timely manner

Excellent all around service, Jorge O. Hernandez was amazing, I've been to dealerships and didn't feel well about doing business with them, but he went out of his way to make me feel comfortable and not rushed into making a big decision, that's way my biggest preference. I thank you all for the great customer service and more

Robert was very professional, thorough, and clearly explained what had to be done, the cost and timing

Customer service was spot on. Smooth from start to finish.

Robert takes good care of me.

Everything from Sales help to service went as planned.

I called and got right in for an appt. They were quick and even washed my car for me!

Five Star Service at it’s best!!!

Everyone was very nice and helpful.

Everything met my expectations.

Professional, Courteous, Efficient

Fast and efficient

I am extremely disappointed with my overall experience at this dealership. I brought my Buick LaCrosse in because it was shaking and felt unsteady while driving. Since this is my first car, I thought going to the dealership would be a good way to ensure proper care and potentially build a relationship with them. At first, my service advisor was polite and told me he would call with a diagnosis. The next day, I received a call and was quoted over $1,000 for tires and over $3,000 for mechanical repairs, including brake pads, a CV axle, and a wheel bearing. When I mentioned that I wanted to call my stepdad for advice, the advisor’s attitude immediately changed and became noticeably annoyed. I simply wanted to make sure I wasn’t being overcharged or having unnecessary work done. I later called back and agreed to have the repairs completed, but asked for an itemized estimate of the costs. I was told they could not provide one and that maybe it could just be “written down and shown” to me, which I found very unprofessional. I’ve been to other repair shops that provide regular updates and itemized estimates—this dealership did neither. I received no communication until I was told the car was ready for pickup. When I was called to pick up my car, I wasn’t even told the final price until I had to call back and ask. At pickup, the cashier was friendly, but that was the only positive interaction. No one gave me my keys, explained the repairs, reviewed future maintenance, or even acknowledged me. My car was left unattended with the key inside, and I had to locate it myself. No technician or advisor spoke with me at all. While the car initially drove smoothly, my check engine light came on shortly after leaving—after I had just paid over $3,000. When I tried calling the dealership, I was placed on hold for several minutes before the call disconnected. Due to weather conditions, I couldn’t bring the car back immediately. When I called again on Tuesday, January 27th, I was told by Andrew that the check engine light had been on when I originally brought the car in, which is completely false. The light did not come on until after I picked the car up. Even then, he claimed there may have been a code present—yet no one mentioned it during the diagnosis or repairs. If a code existed, it should have been communicated and addressed while the car was already being worked on. I was then told that bringing the car back in would result in an additional charge, which is absolutely unacceptable given the circumstances. The lack of communication, transparency, and accountability throughout this entire process felt shady and incredibly unprofessional. I will never return to this dealership and would not recommend it to anyone. I received better service from small, independent shops than I did here. Thank you for turning my first experience getting my first car repaired into an absolute nightmare.

Good communication and willingness to negotiate. Easy sale

First service on GMC truck, service was done on a timely basis. Had an appointment, was going to be late, so called and was told to bring it on in. When I arrived, there were 3 fellows in the service advisors office, 1 just sitting there, 1 playing on his personal phone and 1 on the business phone, Finally the one on the business phone came out and took the keys, to take it back to service, I asked about a paint issue, was told that there was nothing that could be done about it and told me to rub it off with acetone, which I know will remove the paint. When it was done, a cashier asked me who I was and then told me truck was done, not sure how long it had been completed, but it wasn't too long of a wait, Truck was clean when returned to me. Compared to other dealerships didn't seem very professional and some effort should have been made to take care of the paint issue, in my opinion. Will probably be doing my own oil changes from now on.

Robert was very professional. Dealing with me can sometimes be trying. He did well.

I didn’t expect it to take an entire day to do a first service. I was left at work past my working hours waiting on a shuttle. As a longtime GM customer who buys premium GMC vehicles, a loaner would be nice if it takes this long. I wouldn’t care what it is. But I am sure you have an extra used vehicle laying around I could’ve used for the day. I arrived at your place at 6:40am! Also, your technician did not reset the oil life meter after doing the oil change. That’s oil change 101 for today’s modern vehicles. Makes me question what else was glossed over during this inspection. Next service will be at another dealership. And I am about to trade the Acadia for another GMC 2500 AT4.

Best service and care there is

Lane was awesome. No pressure to buy. Everyone was really friendly.

Robert and the entire service staff are always Amazing! This is the main reason why we take both of our Buicks to Marc Miller and why I chose to purchase a new vehicle from here.

Very short wait tome

Great job by Robert in service. Quick and easy!

Very professional and knowledgeable, Jorge and Steve were very pleasant to work with.

great and fast job

Tom Vaughn has been excellent to deal with. But after getting the truck back on Wednesday, Saturday night the check engine light and reduced power light came on.

They did a great job.

My front windshield was cleaned of the film that came with the car when it was purchased. It was so much easier to drive at night on the turnpike from Oklahoma City. I am most grateful for this service.

knowledgeable, friendly and very helpful! I would recommend GM to everyone

Had appointment for 10,000 mile service on our 2025 Enclave. Was in and out in one hour and a clean and nice waiting room.

Robert Murray ALWAYS takes care of my services, repairs. He is the best. I have used Robert for over 10 years, and he is the reason I continue to get my car serviced at Marc Miller. I live 85 miles away from Tulsa, however, I still bring my car back to let him take care of the service on it! I trust what he tells me is needed . I drive a 2016 Yukon SLT with 208,000 miles.. if that doesn’t say how good his service is, I don’t know what would! ⭐️⭐️⭐️⭐️⭐️

Good and timely work. Friendly staff as always. Thanks Mark Miller, ya done good !

Robert always answers all my questions/ concerns.

Setting up an appointment was easy over the phone (prefer that way). Used a coupon the dealer sent me and saved some money on the service! Dealership people are friendly and work was done on time. They made a couple of suggestions for future maintenance to keep an eye on.

I’ve purchased new vehicles from literally dozens of retailers across multiple states, and this was one of my best experiences ever. The team was very friendly, the process was very easy, they understood my time limitations and worked hard to help me. They’ve earned my business to say the least.

Everything went great they got right on problem.

QUICK SERVICE AND ROBERT LET ME KNOW AS SOON AS MY VEHICLE WAS DONE.

Steve Laymeyer was great to work with on the purchase of our 2026 Yukon Elevation. Angel Hernandez was very knowledgeable about operating the Yukon. Both were very accomidaring and professional. Overall, one of the best purchasing experiences we've had!

They diagnosed the problems and since it’s an older vehicle parts had to be ordered. Only took a few days and car was properly repaired in a timely manner.

They washed my car for the first time after an oil change

Great! Service

Everything was addressed as requested

Kept us informed and what is recommended. Also was done within the timeframe we were given. Knowledgeable and very pleasant

Thought I was getting oil change and tire rotation Only got oil change.

It was adverage

The experience was great.

Robert Murray went out of his way to get my vehicle serviced. He was very kind, courteous, helpful, and professional. He always tells me in advance of all my vehicles needs. Marc Miller, you need a lot more people like Robert. Marc Miller, you are number 1 in service. Thank you Robert, and the whole service dept. for keeping my vehicle updated and safe.You all are number 1.

I was treated nicely and my problem was quickly diagnosed and corrected

Friendly, professional service.

Pleasant staff, efficient timing. Also appreciated the service reminder.

They delivered quality products quickly with friendly service at a great price.

Friendly and respectful

Dropped my new 56k vehicle off for transmission issue on my appointment date. Took a week to even look at it. Was given a loaner truck as a disabled older woman. They said they would get me into something smaller, but never did. Once they looked at it they ordered parts, but I had to call for updates. The lack of communication is ridiculous. After a full month they finally got it fixed. I am not happy at all! Unacceptable treatment. Communication is key too!

It was a non pressure experience. They listened and gave me choices. I definitely appreciated that.

It was Ok they changed my oil.

They are not friendly and they wash the car. It's looks they don't care. I am so unhappy with the service

Top notch service department. Tom communicated with me throughout the entire process. I was happy with my service. I will be back.

Robert Murry is great service professional

Knowledgeable, friendly and professional service.

Everything went as planned.

No comment

I was contacted by Eli Lopez after I expressed interest in 2 GMC Sierras that were on the website. I made an appointment with Eli and a deal was struck on a Sierra Denali. Everything went smoothly and all communication was straightforward. David in the Finance Dept was easy to work with and the experience was smooth.

You have an excellent customer service and I love coming there because you take care of your customers

Clean and April was kind and knowledgeable

Friendly and fast!!! Great Job

KIND 8 COURTEOUS

The staff were polite and respectful, but I was disappointed to learn the transmission flush they recommended isn’t what the Buick owner’s manual specifies. The manual calls for a fluid and filter change, but I was advised otherwise. I trusted their certification to follow GM’s standards. I hope Buick ensures their dealers recommend manufacturer-approved procedures in the future.

Found the right suv we wanted priced very good Steve general sales manager and salesman Mike excellent help finding the right one for us. First new car bought .I retired as G.m. tech 45 years

Great service. Very professional and was fast.

Well done as usual

I’m not a huge fan of going to dealerships, but you guys made the process about as smooth as possible. Lane was great to work with and so was George. Definitely coming back for the next purchase.

Wonderful

Easy in, Easy out

Great people and pricing

Marc Miller is always great to work with for purchasing a vehicle but they are astounding in helping you maintain it!

I really appreciate knowing the details of what maintenance needed to be done.

Timely. Courteous. Expert efficiency.

Won’t go anywhere else

Was just an oil change

Robert in service is the best person to deal with. I have been with him for years and he always takes care of my car and explains everything before they do any work. I would trust him with any car problems. Need more trustworthy employees like Robert. I am a widower and he never tries to sell me anything I don’t need.

Robert Murray went out of his way to help getting my ball joints put on my car in very fast time!!! He was very courteous, kind. helpful, and professional , in everything he did!!!!!!!!!!!!! Thanks to the entire service crew for everything they did!!!!!!!!!! Marc Miller is still number one by a long ways!!!!!!!!! Thanks again. Wish all employees a very Merry CHRISTMAS!!!!!!!!!!

This was a great experience.

Great Experience and Communication. Angel and Steve were great to work with and have earned my business for any needs going forward for my vehicle purchases.

Knowledgeable, professional and friendly service as always.

Robert was excellent in getting our appointment scheduled and completed in a timely manner. Work was done well, questions I had were answered and it all took less time than I expected - it's always a pleasure doing business at your dealership!

They did a great job and fixed everything.

everything fine except they left cap off my oil, i noticed my hood was about 1" up and popped hood and luckily they slammed it on the cap so cap was still there.

Steve in Service was excellent and helped us get the items we were promised when we bought the car. He made sure our rear lights (of which only half of the marker and brake lights worked after we drove home 4 days ago) were repaired, the expired air filter replaced, and the used, worn floormats we were given last week were replaced with new ones (as promised). I am not pleased that we had to make another 4 hour round trip to Tulsa to take care of items that should have been accomplished before we drove the car off the lot. I am requesting a complimentary oil change from Mark Miller. We plan on keeping our car serviced with Mark Miller as long as there are professionals like Steve to take great care of us and our Buick.

Quick service friendly service writer

very quick service.

Lane Gabby made the buying decision easy I would highly recommend Marc Miller

Great communication. Professional and quick

Excellent service

Top notch service as usual. Fast today as well.

100% excellent!

My salesman Lane was fabulous 🤗

First time there, everything was Ok. Nice waiting room, work was completed quickly.

The staff was very efficient and kind.

Good

Best Service Department in Tulsa! Fast dependable. I will be back! Pam was very friendly and knowledgeable.

Service department did not seem competent when speaking about the issues that were to be addressed. Sent us away with a tire with 12 psi after a tire rotation was completed. claimed we had a piece of metal in the tire. issue was actually a damaged valve stem that was not damaged at drop off. finding someone to at least air the tire back up was extremely difficult only minutes after we had left (near closing time of service department).

It was fine

Quickly fixed my issue

Fast & efficient

The sales person, Lane Gaddy, is a treasure to both the dealership and the customers. In the last few months I have had the pleasure of purchasing two cars with his help. I hate dealing with dealerships so badly that my last car was a 2002. Lane and his management changed all of that. Turns out I just have to find places that treat their customers with respect. I found that at Marc Miller. The first car experience was when I helped an elderly lady purchase a car. Lane was very patient and accommodating which was important since she was technology challenged. Doesn't even have an email address which now I realize she probably didn't get the survey. I am very happy to recommend this dealership, their management and sales crew to anyone that wants a painfree experience purchasing a car.

I appreciate being able to get my truck serviced in a timely manner and schedule the service into my busy week as well. My truck is important to me and the service department helps me track needed maintenance.

Thank you Rob

All the employees were helpful and very nice.

Always do a great job

Was quick, easy and not stressful at all. Very personable young lady. Beat experience ever.

Very professional and courteous. Just came in for an oil change, and it was done very quickly, completely satisfied.

Had an appointment. Everything done in timely fashion.

On time, good work

My wife took our new envision to the shop because we had picked up a screw in the tire. The service and courtesy that she received was so professional and reassuring. The service department advisor took care of the problem in a very timely manner and we are very grateful.

No thanks

Great service and valuable help for the warranty work paid for from a third party Thanks again. I will be back next time I need service

They had me back on the road as expected and got me checked in on schedule without any delays.

Very good. I was not expecting to leave my vehicle for most of the day, but the dealership made it less painful. Stephen my service advisor was great and very helpful.

I brought my 2024 Terrain in for a recommended oil change and tire rotation. Also I requested the vehicle be detailed afterward because of a hot coffee spill a few days prior. I am very disappointed and dissatisfied with the condition my car was returned to me. 1. The oil life sensor was not reset. 2. Water spots all over front chrome grill. 3. Water spots on windows. 4. Mud/dirt still on mud flaps 5. Coffee stains still noticeable in interior of vehicle. I spoke with the service manager about my concerns. He decided to grab a rag and began wiping here and there. Believe me I will not recommended your service department to anyone nor will I happily return.

Thank You Rob for making my oil change so fast.

Robert Murray took good care of me. It was a timely service.

Eli always takes good care of me when I come to the dealership.

I arrived early Ames my car was quickly attended to. The complete service was performed in 30 minutes. Mr S. Sanchez came out and explained that everything on my car looked good and told me specifically what was done. He was very polite and cordial. I will definitely continue to use Marc Miller for servicing my car. When it was time to pay the person helped me use my reward points towards my payment and recorded my account number on my record so it would be easier the next time. She was very efficient and courteous. Great experience all around!

Fast, efficient

Always pleased with the service & staff when take car in. Still loving my Terrain!!

Always clean and bright. Everyone helpful. This is the 4rd Buick we have bought from this dealership in the last two years. Lane Gaddy is an excellent sales representative. Always helpful and very honest.

Excellent communication. Very happy with the work that was done and the problems found. Best service center experience compared to others

Quick and polite

They got me scheduled for the next morning so I would be able to take the vehicle on a trip the next day.

Very efficient

My car was done and no one told me. It had been done for a while. When someone came in to talk to another customer I asked her and she said she would check on it. When she came back she said it was done and the tech that was talking care of it went to lunch. Then when I went to get my car I had to wait for someone to move the car that was blocking me in. I also asked for it to go through the car wash and it wasn't.

Did not perform the asked repairs. Hid behind some arbitrary GM measurements that did not address the leaning of the truck. Was promised that a regional engineer was going to come to the dealership to lay eyes on and inspect the truck. Instead, they simply called in and had the same measurements performed and said it was "within spec" even though the vehicle is obviously off. Their own advisor said in an email that the "truck was still off". It was in their possession for 6 weeks and then charged me for fixes that did not fix the vehicle. They made me come get it and pay another $1,200 for repairs that didn''t change the condition. I would never use this dealer again and will be sharing across all social and online platforms.

Thank you.

The guys we worked with were polite, not pushy, and very helpful.

Very smooth in and out the door.

To keep it short and sweet...the experience was great!

Lane Gaddy was very helpful and great to work with. He will be the first point of contact when we are ready for our next new vehicle.

Fast service, the lounge was full when we got there and I thought we were going to be there forever but all those customers including me were checked out and back in our vehicle in under 45 min and they rotated the tires

Did good

Had a great experience because everyone, especially Lane Gaddy, were helpful

Lane was great to work with with. One of the easiest experiences I've had buying a truck

Very professional and fair pricing.

Excellent service

Service writer Robert is always very helpful, the work was done on my vehicle as it should be, as far as I know; the girl who took my payment was very sweet, but when I got in my car I noticed that the "key" to my tires was in the cupholder - not a big deal - and when I leaned over to open the glove compartment and put the key back in there, I noticed that the contents of my glove compartment were strewn on the passenger side floorboard. There's not much in the glove compartment because that's where the tire key is kept and I know the service guys get in and out of there, but it was annoying.

Very prompt. Friendly and helpful

Mike Harwell took great care of us.

the staff was friendly, welcoming, & helpful. our salesman was lane who made the process so easy, we were in & out in less than 2 hours!

Great service. Thank you Robert and Bobby.

Robert Murray is an excellent Service Consultant and always take great care of me. I have full trust in him with my vehicles.

Great communication. Consistently good service year after year!

Like the dealership, but I do not like you have CARFAX sending me messages on when my car needs work done to it. Or that I have not done the right work on my car. Robert is a great service department manager.

PROMPT AND FRIENDLY SERVICE

Not enough show and tell on the cars we just purchased. For someone who is not tech savvy it can be hard to find out what all of the things on the car do.

We were treated well during the whole process. Mike Harwell got our deal done before we got there which saved a lot of time. We drove 4 hours to purchase here and it was worth the trip. This dealership was recommended by a family member who has purchased 3 vehicles from them. I will recommend it to others if I get the opportunity.

Robert the service advisor is a kind person knowledgeable

Robert Murray does an excellent job.

Staff was pleasant and courteous. I appreciate all of you, thank you!

Fast and done Perfect

They don't like what they doing. They are not people person. They don't like questions to be ask

Sad to hear my warranty is expired because I really need this fixed but happy to hear that there’s rentals available because I have no way around while my cars being fixed tomorrow

Our salesman, Lane, was amazing. We have bought 2 cars from him and will recommend him to everyone.

Work completed in timely fashion, very responsive

The service went well. However when paying, I shared an email I had received from Buick Certified Service (buick@delivery.buick.com) for $20 off towards a Dexos 1 oil change or $40 off towards a the purchase of a Mobil 1 oil change bcs I am a GM Rewards member, but I was told they could not honor it. The offer expired 6/30/26. They said they needed a code and there is not a code in the body of the email. Then, they told me I should have printed it out. The email says ‘Present this email to your service advisor. Offer valid for your VIN (Last 8): MJ171123 [Offer ends 6/30/26]’. So I was not aware prior to picking up my vehicle that I needed to print the email out. I had coupons I had received in the mail at home, but did not bring them because I had the email on my phone. I felt like this was not good customer service. I have called Buick to address this email as well. Either Corporate needs to better understand how a customer gets an emailed offer fulfilled and adjust the email copy accordingly or local dealerships need to understand Buick customers are receiving these emails and be sure they honor Buick email coupons. Overall, it felt a little bait and switch.

Robert sent mailer suggesting work on vehicle. I ended up getting them all done after speaking to him on the phone. He was very professional and helpful and delivered as promised. The only reason I gave 4 stars was the checkout procedure. It took nearly 10 minutes to checkout and I was first on line. I don’t know if the person was untrained or the system is so burdensome with all the. iPods of papers, but it was causing frustration of many customers behind me. She either needed assistance or the system could use a bit of a improvement

Timely manner well adviced

Robert Murray in the service department and the entire service team is Amazing! They always take excellent care of our service needs for our two Buicks. That is one of the main reasons why I purchased my car there in the past.

Service was excellent

Great service and wonderful attention to all the areas that need attention. Love these folks. Best I have ever had. Thanks so much.

Robert Murray and everyone is always very helpful. I really appreciate the dealership

Amazing!!

Everything went great with my car service

Great customer service! Thank you for professional, expedient work.

We worked with Mike. He made the whole process so easy. We already knew what we wanted. He had the vehicle out front already waiting. Even though we already knew that we were were getting it. He never once was more pushy then needed to be.The finance gentlemen made this process smooth quick and easy as well. We were in and out no problem. I've already recommend this dealership to everyone I know. Great first experience!

Robert is excellent to work with.

Lied to me about my cost. Didn't answer texts. And when I left my tires were set at almost 50 lbs of pressure. All 4. I took a picture and sent it to the text number. Still no response

Still not happy with this dealership

They did a great job.

Prompt and courteous service. Done on time.

Work was complete on time, waiting room was clean with coffee and donuts

Great, fast service

I received a manufacturer coupon for $20 off. Receptionist asked for me to forward the email, which I did 3 times and she never received it. Due to not being able to wait I paid in full. 2 hours later my tire monitor system light came on, which the person I spoke to when I came back insinuated that I ran over two nails and needed to go to a tire shop. I told him the system needed to be recalibrated which required me to come back today. Both are out of my control. However, it would have been nice not to be essentially blamed that I ran over two nails. When I came in today the person who helped with my oil change quickly recalibrated the monitor system.

I asked for vehicle check up in addition to oil change. Recommend & explained additional maintenance services.

Friendly staff who completed my maintenance as requested in a very timely manner

In and out fast. Thank you Pamela

Robert Murray did a great job on getting my vehicle serviced. He was very courteous, kind, helpful, and professional in telling me what i needed to do to my vehicle now and in the future. Thanks to the entire service dept. at Marc Miller. You will always be no. 1 to me. Thanks again, Robert, for all you do!!!!!!!!!!!!!!!!!

Send complaint into service manager which has yet to be answered

Jorge and Dave were awesome! A lot of the paperwork and pre-approving was done beforehand and it saved a ton of time. I drove in from Norman to make this purchase, so I appreciated their diligence.

Your service was markedly improved from last time. The automation of documents through electronic delivery is wonderful. The service manager has more time to spend with your clients. The waiting area was refreshed and clean. I’m glad I went to the dealership again.

Jorge, is fantastic. He is one of the very best salespeople I have ever deal with. As long as he is with your dealership we will purchase vehicles from you.

Making appointment was easy. Was able to get my car in and out for service on time, and get on my way.

Wait to get in to my appointment was too long - 10 minutes for scheduled appointment. No one available to check us in. Wait to pickup the car was way to long. Cashier not available for 20 minutes. Never had this at other dealerships. Won't be back. Not the only show in town.!!!

Very fast and courteous they got me in and out and done a good job.

Robert got me in and addressed all my concerns

Pam took great care of me and my service needs. Thank you for the prompt and professional service.

Do good work

When I brought my car for service back in April, my tires were at 4/32. When I brought it in June, they were at 7/32. Somehow they either grew tread or the mechanic lied. I was prepping the car for a 3k mile road trip so I went to another place for a second opinion. They were at 3/32. I had the other shop put some new tires on so my car would actually be safe to drive. I will never be back to this dealership again due to them taking convenience over my families safety.

Helped track down the perfect car and were super easy to work with.

Made an appointment for oil change and rotation and they were done within 30 minutes.

Best experience, Terry and Eric are awesome, had a bad experience with the collinsville gmc over a 2024 used ultimate Denali and Terry (who I’ve done business with for over 19 yrs) says come see me, sold me with GM incentives a brand new ultimate…. Highly recommend is still not enough rating in my opinion…… never a bad experience with sales department of Marc Miller

Robert Murray is very knowledgeable and professional.

Great Job

5 star all employees

I told them I wanted 3 things. 1. How much I wanted for my trade. 2. The interest rate I wanted. 3. No running back and forth. Give me the best deal up front. I feel I got all 3 of these things. The transaction was easy and I am pleased. Jorge was outstanding and patient and very kind.

The whole thing went great, very helpful staff and George Hernandez the sales guys was, for the second time, most helpful and made everything happen easily.

Great experience buying my car at Marc Miller! Mike and Steve made the process easy. I would highly recommend!

It took 2.5 hours for the service to be completed. The quality is always great, but it has taken 1.5-2.5 hours the last two times I have gone.

They were friendly and explained what they did.
