The customer service at Dave Sinclair Buick was fantastic! They had a lot of work to do on my vehicle. The work was flawless. The level of communication during the whole process was superb. Eric in the auto body shop showed what excellent customer service should look like. I cannot thank them enough for the level of service the team provided.

Went to look at a Rav 4.
Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Easy, no pressure purchase
Sales consultant; Bob Reasoner, helped me with the car I was looking for. This dealership has a no rush, clarity policy that aloows you to inspect the car to your satifaction and present you with a car that has been safety inspected & detailed. Qualification and rates were resonable.

Nicki was wonderful, I will recommend her to everyone I
Nicki was wonderful, I will recommend her to everyone I know that are in the market for buying a vehicle. Jarrod was also fantastic to work with. Both very personable and made the process very pleasant when it had been made dreadful from trying to deal with other salesmen at other dealerships. These 2 were excellent. I've never had a better car buying experience. I'd been to 4 other dealers who wouldn't budge on price for the same vehicle. I was able to drive my brand-new car off the lot for $6000 less than the competitors offered WITHOUT a single haggle!
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Great Experience
After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

I had the absolute best experience at AutoNation in St.
I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.
Reliable and comfortable.
I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

WOW - I am a forever customer now. AMAZING TEAM!
The staff could not have been better. They did not play games. they knew what they were talking about. They offered me more for my trade than 4 other St. Peters / West / South County Dealers included Lou Fusz, Bommarito and Sinclaire. They stayed late to get it done and even went to buy batteries for my remote. They also have the FOREVER warranty that is amazing bumper to bumper as long as you own the car. Totally worth the drive. These guys were so easy to work with. I wouldn't go anywhere else. They even have concierge service for free including bringing you a rental even for routine maintenance! You won't find a better deal, better people, or better service in St. Louis...maybe anywhere. Can not say how impressed I am with these folks. After weeks of car shopping they closed the deal with style! Thanks guys!
Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Craig was awesome... seemed like he actually cared about the customer and wasnt just trying to make a quick buck. I
Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Ryan did a GREAT job as did everyone else.
Purchased a 20yr old Nissan from Ryan, he and the team there gave me as much information and the condition of the vehicle as was possible based on the age and of course based on the age the car does have its issues which I had expected, but Ryan did a great job of working things out and as I arrived really late he and the necessary people to finish a deal were there and ready to help. I picked the car up the next morning with a full tank of gas ready for my 300 mile trip home. They gave me a great deal on the vehicle, far below what they were asking all said and done out the door.
