About Us

Thank You for Choosing Williams Buick GMC

Williams Buick GMC has been Charlotte’s family-owned Buick and GMC source since 1937. We sell more Buick and GMC vehicles by volume across the Carolinas than any other dealer, and we’re proud of the vehicles we sell. That’s why we were named one of only 20 Buick Dealers of the Year in 2020, and a GMC Dealer of the Year in 2019. Make the trip from Fort Mill to get professional and friendly service that’s dedicated to giving you an exceptional shopping experience.
