My experience with Hayden was great.
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.
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Fabulous experience from beginning to end.
Fabulous experience from beginning to end. Ron Martin was welcoming and truly interested in helping me find the car I wanted. His friendly - no pressure approach made the car buying experience easy and fun.

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.

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.
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

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.

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.

Wonderful staff, easy to work with. Everyone was very knowledgeable and was able to answer all of my questions and concerns through the entire process.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.
