What an amazing experience. Convenient location, respectful of my time and every single employee in the dealership was so friendly. Even the owner took the time to acknowledge and speak with me. Blake was a great sales expert. He is super low pressure, honest and met all of our needs. I love my new Buick Avenir. If you wanna buy from a friend and feel like part of a family I recommend this Buick dealership for everyone.

My husband and I had been out looking for a new(to us) SUV and had been at other dealerships before we stumbled upon this one. O’Fallon Buick GMC was the best car buying experience we had dealt with. We were greeted by sales, Devan Wall once we entered the lot and it was a pleasure to deal with him. He was very genuine, along with everyone else we spoke with that day. Buying the vehicle came with great ease. We had to come back to pick the car up the next day (although it was offered to us for it to be delivered, free of charge!) and it happened to be storming with the chance of hail and Devan stayed in touch with us, sending us pictures of our Yukon pulled inside the shop to prevent any damage. That gesture meant a lot to us. We would recommend this dealership and Devan to anyone!

Justin Redfering knocked it out of the park. When I stopped in looking for a new car. Upon arrival he had the 2 cars I was most interested in up from ready for test drives. Both cars were amazing but not exactly what my wife and I was looking for. With Justin suggestion we looked at a Terrain. He even remember from a small conversation I wasn’t a big fan of the all black interiors. So with the outside color being black like I wanted. He showed me the platinum interior Terrain Denali and the rest was history. Thanks for all your time and help!! I will be back for future purchases!! Highly recommend going and seeing Justin!! :)
