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!

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!

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

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 location and the perfect setup, easy in and out. They know what they are doing and have state of the art equipment.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Work was done on Schedule, actually completed prior to estimated completion time. Both my Service Advisor Jerry and the Tech, came to me afterwards to make sure everything was Satisfactory. Thank You

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Great team! I Was a walk-in. Friendly helpful staff - went into look at a Canyon. I found the truck online. Salesman TJ helped with locating the truck and brought it up to the showroom. Even washed it prior to me seeing it ! Great financial staff. Quick and easy!! I Will return in the future for more vehicles.

This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

My salesman Aaron Voege was excellent,courteous and I will recommend him to all my friends.. He made the transition from my Altima to my new Rogue perfect. Thank you Aaron..

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

I liked that Keith listened to what I needed and wanted. He didn't try to upsell me or get me to spend more for no reason

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Tyreese listened to my wants and even though my initial choice sold prior to my arrival, he found me a better option. He was very knowledgeable about the cars features which made me love my car even more.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Excellent service, fast process, and very friendly staff. Truly a great experience for a new buyer. I do recommend Angie Flamn!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

I received a welcome greeting on arrival and was taken care of immediately. Brian Brody, the sales specialist, warmly welcomed me and pointed me in the right direction regarding my preferences for a car. He offered other car options to consider. I ended up purchasing one of the other car options. In the end, I was grateful that he pushed me to see everything. The wrap up process was professional and friendly, dealing with the sales manager and finance manager. All in All, I love my new 2026 GMC Terrain

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Loved the whole experience , would recommend the dealership to all my friends, exceptional customer service,ok, ok, ok,ok, ok, ok, ok, ok, ok ,ok ,ok..

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

Bought a second car in two weeks for my twins! Great service and prices. Will for sure be back and keep buying all our cars from them!

Bought 2012 in 2021. I have put 18,000 miles on it. Had to do brakes, CV joint, and the thermostat. Otherwise, it runs very good.

Thank You Chad Sigsworth for your help with the purchase of our used car! You made us feel like your own family, no pressure to make the purchase only the truth! We are very satisfied with our Escape!

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

I worked with Scott and Jim, both very friendly and easy to communicate with. Got to the dealership and didn’t spend more than 30 minutes there. Very smooth and pain free process!

Great vehicle. Has great features and it is a very smooth ride. It is quiet on the road. Great gas mileage (over 28 mpg combination town and road).

Jim and Ken did a fantastic job. They were patient and answered all my questions. They made me feel like the entire dealership was open to me. They introduced me to the service manager. The car is incredible, better than my BMW X5.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Josh M helped me in service. Had a great experience! He has wonderful customer service skills. He is very knowledgeable!

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

Great experience at Carmax at Mid Rivers in St. Louis. We were looking for a low mileage 2014 Toyota RAV4 and we found the SUV we wanted on the lot. In total it was the fastest we have been in and out of a dealership after buying the SUV.

Got it for the ride ,comfort,great gas mileage on trips,can do a 750 mile trip and not be warn out from the ride.Can carry a lot of stuff .All the different options are great
