New and used 2026 Buick Encore GX for sale near Frontenac, MO

Everything was great from a service prospective. Took off a star for the 3% credit card fee. Service is not cheap at the dealer and to tack on an extra 3% is unnecessary. In addition I have a GM credit card and to charge an extra 3% at the dealer pretty much makes the card useless. I?ll probably just cancel it

COULDNT ASK FOR BETTER SERVICE, GO SEE JOHN IN SERVICE TO GO ABOVE AND BEYOND YOUR NEEDS

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.

As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!

Conan Thomas was my service advisor and the service was excellent. Took care of everything and made this service call as easy for me as possible. I will always go back to Sapaugh.

They did exactly like they said. The saved me over $2500 over the next closes price. The delivery was flawless and respectful. When buying a GMC truck this dealership needs to be on the list.

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

From purchase to first service, no complaints. My purchase was smooth and easy with Nicki, and my service was fast and efficient with Heather! Thank You!

I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one

New car buying made easy. The entire deal was completed through email and over the phone. Jason Davis was friendly and helpful. He answered my questions in a timely manner and made the experience simple and hassle free. The vehicle price was straightforward with no haggling required. I felt like I received a very fair trade in on my truck.

Our salesman Bruno was the best by far! We didn’t feel pressured to buy a vehicle, but at the same time we felt safe buying a car from him. He was very informative and made sure all our questions were answered. He called a week later to check on the car and let us know if we need any further assistance to reach out. I have recommended my family to go see Bruno at Cardinal Buick!
