Been to many different dealerships to have my autos serviced. Ofallon has the BEST People for checking in for service. They are super nice, polite. helpful. and treat you like a Valued customer. Had questions that they answerrd very professionally in a manner that I could understand. They even washed my vechile for me. When people ask me where I got my beautiful Acadia I proudly tell them O Fallon Buick and GMC and how to get there.

We were really satisfied with our experience at O’Fallon Buick GMC. Our sales assistant Hakeem was very knowledgeable and extremely courteous and pleasant. He worked hard to help us get what we believed was a fair deal on our new Yukon.
The dealership in general was a wonderful atmosphere and gave the impression of caring for their customers!

Worked with Chris Cayse. Communication was straight forward - no BS. Was able to do lost everything online. Upon arriving at dealership, did final test drive, was only presented F&I options (no pressure or incidental add-ons), signed paperwork and on our way in about an hour.
Only downside was that the floor liners had not yet arrived, but have commitment for that to be completed.

Patrick was great. Lacked a few things on Sticker. Called service twice in one day. No return call. I feel when I pay cash for a new auto I should get better service.
