O'Fallon Buick GMC review
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.

Overall good drove over three hours to arrive, pain that
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.

Dave Sinclair Buick GMC review
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

The salesman I dealt with, Rob Fulmer is one of the best.
The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!
