Great experience with Carlos
We purchase a new vehicle at least every 3 years. . .so we have had quite a bit of experience with car salesmen. Carlos Lopez is by far our favorite. He listened to what we wanted; was attentive (even though he was very, very busy); and made our experience a great one. Dan handled our finances and he was a nice surprise. This is where you can sometimes feel pressured into purchasing a maintenance plans even when you had not intended to. He presented us with options but did not pressure us in any way. Refreshing. Great overall experience. You cannot go wrong with Bommarito Nissan West County. They have a nice selection of vehicles, nice facility, and as I already mentioned--first rate staff.
Our AT4X has been an excellent mid-size truck.
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.

Had my 2024 Canyon for exactly one year.
Had my 2024 Canyon for exactly one year. Not a single real issue once over the air update was done and that only affected the radio. It was an AT4 in desert sand metallic. I traded it for a 2025 Acadia, as I missed life in an SUV. However if you want a truck, I’d highly recommend it and specifically the AT4 model. It’s got meaty tires for pothole protection, it’s able to tow more than you can imagine, it looks super amazing and you’ll have lots of thumbs up and positive comments when you get gas, etc. updated tech was more than you could ask for. 4WD auto mode worked flawlessly. Engine had a nice little growl that I miss too. Let me say if you are a truck person or want to be a truck person, it’s a perfect mid size truck. Mine was 100% and am missing it yes but love the Acadia because it’s also a great vehicle. Got the AT4 Acadia and for my situation it’s perfect.

Its a decent car, but on a car frame.

My experience with Hayden was great. He was knowledgeable, courteous, and willing to present my offer on the vehicle. I ended up purchasing in my home state but would highly recommend them based on my experience with them.
I have owned my Acadia just under one year.
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.

My Work horse.
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.

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!

Always on time and always finish pretty close to the time specified. Clean shop and friendly professionals to help with your needs and questions, or concerns.
Stylish and comfortable.
Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

Her performance was exceptional, as was all of the aspects of my service with Laura GMC in Sullivan Mo!!!!

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

Love love LOVE
I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.
