Our Legacy of Excellence

Heritage Buick GMC first opened its doors in 2005 as a Buick, Pontiac, and GMC franchise in Terrell, TX, under the entrepreneurial spirit of Robert Bobo. The dealership relocated to Rockwall in 2008, where we continue to grow and serve drivers throughout the greater Dallas-Fort Worth area. 

Amid the evolution and fast pace of the automotive industry, our roots remain strong as a family-owned and operated dealership committed to the values that set us apart from the beginning. Our mission is simple: to provide every customer with an extraordinary experience defined by integrity, transparency, and a genuine commitment to service. These values define everything we do, from your experience on our showroom floor to our service center. 

Our motto says it all: "Click, Call, or Text and we'll deliver anywhere". It's a promise we keep every day to every customer who walks through our doors.
