New and used 2026 GMC Terrain AWD AT4 for sale near Saint John, MO

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.

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.

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.

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.

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.

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.

Great service!I was picked up at the airport in a very timely manner.I recommend this dealership to anyone I meet that is looking for a vehicle.

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.

Bruno was awesome and determined to get me the vehicle that I wanted. Which he did. he was selfless and made sure that everything was convenient for me. I highly recommend anyone seeking a new car to go to Bruno.

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!

Total definition of teamwork love it very understanding and will work with you!!!!!! Love my car family
