I was impressed with O’Fallon Buick GMC! The price was straight forward, honest and a great deal. Paul M. was our sales rep and did a great job handling things for us. I’m 60 years old an The price was straight forward, honest and a great deal. Paul M. was our sales rep and did a great job handling things for us. I’m 60 years old and have bought many new vehicles over the years. This is the first dealership from any big 3 auto maker who actually meets customers and thanks them for their business. Derrick Sewell is the kind of owner I would die to have if I were the CEO! He’s got the right recipe for continued future success. I flew from northern Maine to St Louis to pick up my new 3500 and will be an ambassador for the brand going forward. Thanks to entire O’Fallon Buick GMC team! More
