    Drove truck in a day early and they fixed it a day early. Awesome service! They noticed, due to temperature change, that the tires were low and they added air to the tires. They notice the little things and fix it.

    Very comfortable process start to finish. Nick was a great ambassador for the dealership. Very knowledgeable and eager to answer all questions. Fair negotiation on both new and trade. The whole team gets involved at the dealership. I would not hesitate to recommend O'fallon dealership.
