New and used 2026 Buick Encore GX ST for sale near Clarkson Valley, MO

Bruno was amazing to work with. He was attentive and explained the process in detail. He went over and beyond to ensure all questions were answered and that we were satisfied with the purchase. Even after the purchase he checked in and offered assistance. I would recommend Bruno for your next car purchase. Overall an honest professional.

Service Advisor, Kevin Gromer, was very helpful and professional. The tech, Ryan Hellrung, worked through lunch to complete the repair that day. Hats off to both of these Lou Fusz employees.

Always a pleasant experience. I never have any complaints about service or customer service.

Gus and his crew were amazing. I bought this pickup off the internet, and they picked me up at the airport and 1 hour and 20 minutes I was headed home.

Got transportation to home while repairs were being made with a nice guy. The repair was not as scary as I thought it would be.

Easy process. Dmytro was very helpful and accommodating. Follow up was timely. Found the car I wanted online, submitted a request for information, received a call back immediately.

I purchased a new Samsung S25. The Google GPS app on the phone would not connect to the GPS display in the Equinox. The Phone store where I purchased the phone could not get it to connect and neither could I. I and others thought possibly GM software was out of date. So, I brought the car to Sapaugh GM. The tech determined the software in Equinox to be the most recent upgrade. And after some troubleshooting decided to problem might be the phone's Google GPS app. He removed the GPS app from the S25 and reloaded it...the result was the GPS is now operational. I appreciate and respect the troubleshooting and repair capability of the Tech which extended past the GM boundary to an associated vendor. I use the GPS and consider it a tool for convenient, safe driving. Thank you Dan McHale

Bo is a asset for your dealership with his professional manners of taking care of customer needs when they are purchasing a car to fit their budget of completing a deal of customer satisfaction of driving it off the lot.

From the first time I set foot on the Buick car lot, Beau set off a great car search experience for me and my family. Not only was he awesome but everyone I met there was warm, friendly and caring. The O'Fallon Buick GMC not only brought back my faith in a car salesperson but also purchasing at a car dealership. From the salesman to the financial department each person took time to make sure you understood exactly what was happening. Hopefully, I want have to purchase another car for a while, but if so, I know where to go.

Walter Washington was excellent. Very nice and kind. I would recommend him to all family and friends.

Best kind of dealership. No pressure sales and mindful of your needs as a customer. We will definitely be repeat customers.

Great experience service Joe is helpful and very friendly would recommend him to everyone. Dealership is very clean and waiting time is always very short for normal service work
