O'Fallon Buick GMC

Very friendly staff salesman was very knowledgeable and explained things .. I would definitely recommend this dealership to my friends and family..

Easy scheduling and quick service/repair and was allowed to keep the vehicle there for several days while out of towm

As soon as you step inside the showroom floor is so beautiful. I was greeted with more than one friendly kind and courteous people. Paul went above and beyond meeting my expectations. Everyone was very friendly.

Great experience!!! This was our second purchase from O'Fallon Buick GMC and we will definitely come back. Roger is the best!!

Paul. Was great to work with, very attentive and answered all my questions. Once I realized, the first truck, I was planning on buying, was only a two wheel, version, he went back onto the lot and forwarded me the information on the 2 he had, that had the 4 wheel option. Once. I had his input, I made my buying decision and told him, which model I wanted. Paul, did a great job. Thank you Dan Kessler

Blake was an awesome salesman and a very nice dealership! Very easy to work with!

Very nice dealership to work with! They take good care of their customers and check in after the sale to make sure all is good with the new vehicle.

I don’t think I have ever been treated and helped at any dealership in all my years as I was at O’Fallon! The sales person and the finance person was very helpful and prompt at their jobs. I was at the dealership for less then 2 hours and on the road with my dream vehicle. My hat goes off to you all. I’m sure glad I drove 2 hrs away to get my vehicle, it was worth every mile. My sales person (Christy) help me get everything done on the phone and emails. So by the time I got there all she had to do was help me set up my phone for my GMC app, then I went to the finance office then I was done! Great job.
