Better Customer Experience

The store's name does not change as part of the sale, in keeping with Porsche's dealer naming standards; ownership is what's changing, not the team, the inventory, or daily operations.

Group 1 is bringing in Nigel Slack, currently General Manager of its Porsche Westwood store, to lead Porsche Atlanta Northwest, giving the Cobb County store a GM with existing Group 1 Porsche experience from day one.

"I've run a Group 1 Porsche store before, so I know what this company expects and what it's willing to invest to back it up," said Nigel Slack, incoming General Manager of Porsche Atlanta Northwest. "Cobb County customers are going to get the same Porsche experience, just with a team that's already proven how Group 1 operates."

Porsche Atlanta Northwest continues to serve customers from its existing location at 2501 Windy Hill Road SE, Marietta, GA 30067, supporting customers throughout the Windy Hill Road corridor in Cobb County, near The Battery Atlanta with new Porsche 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.
