Above and Beyond Customer Service
This review is in full support of Clement Hyundai – a dealership located in Wentzville, MO – which has shown remarkable, above-and-beyond customer care. At the end of our leasing period for a 2020 Palisade, my wife and I purchased the car outright. The transaction was handled smoothly and thoroughly by salesman Jeremy Null. Following that, our car needed to go through a few inspections for the warranty coverage. In doing that, there was a faulty wiper installed -- requiring the car to go back in to get it fixed. While this could have been a very frustrating experience – as we live more than 30 miles from the dealership – the team at Clement Hyundai went above and beyond for us, recognizing the inconvenience. Especially Jeremy and General Sales Manager Patrick Piper. They picked our vehicle up and delivered a loaner, as well as provided other coupons etc. to make up for the situation. When my wife realized she left my daughter’s dance recital tickets in the glove box, they drove out to our home to deliver them to us. That’s the kind of operation they run: one that has the customer at the center of what they do. I’ve never experienced such superior customer service from any other local dealership – and I’ve owned BMWs, Audis, Toyotas, Hondas, Fords and other makes and models. Clement is a first class operation and should be super high on your consideration list for purchasing a vehicle or getting service.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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.

This review is for Jason Gross service manager. I needed an engine replacement in my Ford edge due to coolant intrusion and after talking to Jason within a few days, he had ordered to parts. I brought the car in and a week later I picked it up and it’s been running great ever since then. Thank you again, Jason for all your help you made all the difference in the world, getting this done right and in a timely manner, thank you ! Jerry D.

Andrew Chavez is a step above! He was quick to respond to my inquiries and basically had the deal made before we traveled 409 miles from Arkansas. He has followed up by mail, email, and text to assure we are satisfied. Very pleased with him. The finance person (I think Ryan) was also very good at signing. Have already recommended to friends.

I felt they were honest 1st of all.
I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.
