Best car-buying experience I have ever had in over 50
Best car-buying experience I have ever had in over 50 years of buying automobiles. It was simple, straightforward, honest, no-frills (read no added costs), and the large selection meant that I was able to get exactly what I wanted. Online shopping and negotiating was very easy with no surprises when I reached the dealer to make the purchase.
This is a very beautifu vehicle, very dependable but the
This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

New car buying made easy.
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.

Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.

As usual, very good service. Chad Boxdorfer was there as soon as I got out of the car. He was very polite and courteous. Got the car serviced and ready to go in the time he told me. Dave H.

Everything was great from a service prospective.
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

From the first time I set foot on the Buick car lot, Beau
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.
