It is finished in Chalk over black leather and Race-Tex, and equipment includes a seven-speed PDK dual-clutch automatic transaxle and a limited-slip differential with Porsche Torque Vectoring as well as the Sport Chrono Package, 20″ Cayman GT4 alloy wheels, a rear wing, bi-xenon headlights, heated power-adjustable seats, dual-zone automatic climate control, and Porsche Communication Management. This 718 Cayman GT4 has 7k miles and is now offered in New York by the selling dealer with service records and a clean California title in the seller’s name.

The car is finished in Chalk (M9A), and features include a rear wing, bi-xenon headlights, side air intakes, and dual exhaust outlets.
