We at O'Fallon Buick GMC are so excited to be joining the O'Fallon community!
While our roots are in our hometown of Greenville, SC, with many years of experience and three generations working within our family business, we knew that it was time to expand. In January of 2019, we had an opportunity to travel to O'Fallon, MO and the surrounding areas and instantly knew that we wanted to join the O'Fallon community.
As a family business, we are most interested in ensuring that each and every customer has an excellent experience and always feels welcome in our state-of-the-art, family-friendly atmosphere. The satisfaction of our customers and employees always comes first, with value and integrity at the forefront of every interaction.

Whether you buy with us or not, we want to get to know you, taking our time to discuss your interests and hobbies, lifestyle, budget and aesthetic preferences to make certain that you make the best investment for you and your family.
We proudly offer a wide-range of new cars, notably new Buick and GMC inventory along with pre-owned cars, trucks, SUVs and crossovers. We also have a highly trained auto-repair and service department which will help you to keep your investment performing at its best.
O'Fallon Buick GMC is also dedicated to contributing to the O'Fallon community. We know that it is the support of the O'Fallon community that will be the key to our success, and we are committed to finding as many ways as possible to give back.
