I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Great vehicle purchase
i was very satisfied with my sales person, Darryl Herndon. We were able to arrive at the sale price of the vehicle in a professional manner.
Perfect for us!
As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

Great Team!!
I had a great experiencing purchasing my car from BMW of West St. Louis. Dawn D. is an excellent person to work with. My purchase was remote and she acted as my eyes and ears, providing a trustworthy assessment of the vehicle I selected as if it were her own. She answered questions, made a video and was readily available to answer questions leading up to and through the purchasing process. The shipping process was seamless with a fast turnaround time. Armin H. was great on the purchasing side of the process. Extremely detailed and clear on cost, warranties, etc. All around great team to work with!

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

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.
Denali made the difference for us
We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

CarMax made the purchase of my vehicle run smoothly, without having to go to the Division of Motor Vehicles. They addressed my concerns promptly and, when new keys had to be made, offered a "loaner" vehicle until the problem was fixed. I recommend CarMas to everyone!

Very casual and friendly. The salesman had all the history of the Escape, which put me at ease in finding him trustworty.
Great Truck
GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!

Great Pick-up
Bought this 2016 GMC Canyon (4cyl) at car max in 2017 . It was part of a commercial fleet and was well taken care of and low mileage . I’ve only have had one problem and that was in the engine cooling system where I had to replace two hoses and a goose neck . While repairing that I noticed an oil leak around the valve cover so I replaced the gasket . It was under warranty still ( just happened in Jan 2024 ) . I could have repaired it myself but who wants to get all dirty when it can be repaired by GMC at little or no cost to me. It still has 6 months remaining on warranty ( I did purchase from CarMax) hoping it does not need any further repairs . It is 8 years old and according to its records this is the first repair other than natural repair items that had ever been needed . It rides well pulls my utility trailer fully loaded just fine . I also have a 2000 Ranger that I had to replace the tranny on when it was just a few years old . It has never needed any other work. I believe the GMC will last me for years to come . But you never know so I will be buying another after market warranty on it when the time comes . I’ve already added that to a 2015 vehicle I own who’s warranty had expired . I’m a old school mechanic I can repair olde vehicles easily ( compared to todays ) I’m also a former Turbo Prop Mechanic from the Air Force and worked those motors for almost 29 years . I had worked on Piston Air Craft Motors for a few years before the change . A lot like a car piston motor in many ways . Two kinds of piston motors on Air Craft . Line a cars block or a receptacating motor( Round) . Very easy to trouble shoot vs Turbo Prop. Just letting you know that I have experience as a mechanic and know a real problem vehicle when I see one . Would buy a GMC canyon again or maybe go larger due to my new 42 foot long Camper I have rec bought .

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.

I only have 700 miles on it so far but it’s been fantastic. I had a 2020 before this one and was fantastic also. GM is the way to go.
