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

Brian Reis did a great job.
Brian Reis did a great job. My husband got a new truck and Brian helped us find the right truck and walked us through the whole process
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

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Bought the car I had researched from Suntrup KIA.
Bought the car I had researched from Suntrup KIA. The salesman Moe was way more than helpful.every one I dealt with was super helpful friendly and seemed very genuine. Moe spent as much time as I wanted showing me features. And even would explain more about her telluride that she bought somewhere else. I have bought many cars in my life. But I can honestly this was my best car buying experience. They all did try to meet my terms and I left feeling I got a great deal. And I did.
Its a decent car, but on a car frame.
Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

Ron, and the entire staff are first class! My wife and I flew down from Minneapolis. Ron picked us up at the airport. We took the vehicle for ride & within an hour and a half, we were on our way home. The smoothest transaction I've ever had buying a vehicle.
Bought 7 over the past 21 years!
On my 7th one. That should say it all. Quality crafted, full of great features, super smooth ride and plenty of room for up to 8 people plus a ton of gear.

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!

Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.

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.
