Lou Fusz Kia review

I bought a 2026 brand new Sportage from Ryan.

I bought a 2026 brand new Sportage from Ryan. From the minute I walked in it was the best experience I have ever had. Ryan was extremely patient as I was not sure what car I wanted. I received everything I asked for with a smile. I felt like I was valued as a customer. Five stars definitely!!!!

AutoNation USA St. Louis review

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.

Clement Supercenter review

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

I purchased the new 2025 Kia K4 EX during late August for my wife to help celebrate our 55th wedding anniversary, and she simply just loves driving the car with all of its modern safety high-tech features, its comfort, and impressive driving performance. I've nicknamed the car "The Batmobile" with its Aurora Black Pearl exterior paint and stylish features that make this car stand out from other sedans that are in the cost-effective $20,000 - $30,000 price range. Plenty of room inside the car, a quiet smooth ride, and adequate acceleration whenever may be needed (e.g., entering onto a highway). The car comes with Kia's standard 5 year, 60,000 mile full warrantee, and 10 year, 100,000 mile powertrain warrantee which is still very generous of KIa.
