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

Everyone at the dealership was amazing!
Everyone at the dealership was amazing! They answered all of my questions, made me feel comfortable, and confident with everything! I definitely recommend this dealership to anyone looking for a used or new car.
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.

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.
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

Amazing Rental Department
Came in for a repair on my vehicle and was also getting a rental the rental department went above and beyond to make sure the vehicle was clean and disinfected and ready for me I was in and out of there in no time at all will definitely be back because of those young gentlemen.
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.

I recently had the pleasure of purchasing a car from
I recently had the pleasure of purchasing a car from Suntrup Kia South, and I can’t express how satisfied I am with the experience. Despite being a thousand miles away, their professionalism, transparency, and warmth made me feel right at home. From the moment I connected with Moe Saad, I knew I was in good hands. Moe exemplified the epitome of a top-notch car salesman, providing me with reassurance and guidance every step of the way. My search for the perfect EV9 led me to many dealerships, but none matched the integrity and authenticity of Suntrup Kia South. Moe and his team went above and beyond, offering red carpet treatment without the need for an actual red carpet. Even while under the weather, Moe ensured a seamless transaction, passing the baton to Dzenis, who continued the stellar customer service. From start to finish, every detail was meticulously handled, including a thoughtful conversation with sales manager Dave, who ensured my satisfaction was met at every turn. In an industry often plagued by deceit and gimmicks, Suntrup Kia South stands out as a beacon of honesty and excellence. It’s rare to find such a level of service and transparency, and I can confidently say this was the best car-buying experience I’ve ever had. Despite the distance, I’d make the journey again without hesitation. If you’re in the market for an EV9 or any vehicle, do yourself a favor and visit Suntrup Kia South. You won’t be disappointed. Hats off to Moe, Dzenis, Dave, and the entire team for exceeding expectations and setting the bar high for customer satisfaction.
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

Pleasant Experience
The lease on our car was up and a friend recommended Suntrup in South County. Since we were up that way we decided to check it out and were greeted by Zach Seiler at the door and we’re pleasantly surprised by his knowledge, patience, and low pressure salesmanship. In a relatively short time we were transferring items from our old car into our new 2021 Volkswagen Jetta-which we really did not plan to purchase that day. And by the way Zach helped us with that, too
Love my GMC Terrain!
I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

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.

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.
I bought this truck new 8 years ago (and 77k miles).
I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

So far I have been enjoying my 2025 GMC Canyon Denali.
So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

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.
