Former Hennessy Cadillac is among the dealerships now operating under Group 1’s ownership
ATLANTA, Nov. 11, 2026 /PRNewswire/ — As part of its ongoing nationwide initiative to unify its extensive network of dealerships, Group 1 Automotive, Inc., a Houston-based automotive retailer with dealerships across the U.S. and U.K., today announced that Cadillac Duluth, formerly Hennessy Cadillac, is now part of the Group 1 network, following the company’s acquisition of Hennessy Automobile Companies’ Atlanta-market dealerships, which closed Oct. 19, 2026.
The renamed store keeps the same showroom, service bays, and sales team customers already know, now with a direct line to Group 1’s national resources.
Backed by the scale, resources, and expertise of an international automotive retailer, Group 1 Automotive remains focused on delivering the personalized service and community connections that define the local dealership experience. Learn more at Group1Auto.com.
Better Customer Experience
In keeping with Cadillac’s dealer naming standards, the store will operate as Cadillac Duluth rather than carrying the Group 1 name on the building. Ownership is changing; staffing, product offerings, and day-to-day operations are not.
Group 1’s purchase of the dealership adds a Gwinnett County luxury rooftop to its Southeast footprint, pairing Cadillac’s domestic-luxury lineup with the operational standards Group 1 applies across its dealer network.
“Cadillac’s lineup has changed a lot over the past few years, and this is one more step in that evolution for us,” said Gerry Martel, General Manager of Cadillac Duluth. “Our customers can expect the same walkthrough and the same follow-up calls, and now a parent company that can back bigger investments in this store.”
Cadillac Duluth continues to serve customers from its existing location at 3377 Satellite Blvd., Duluth, GA 30096, supporting customers in Gwinnett County with new Cadillac vehicles, pre-owned vehicles, certified service, parts, and maintenance support.
The dealership’s team remains in place as the location becomes part of Group 1’s broader retail network.
