This lovely 718 Cayman GT4 is finished in the highly saught after Crayon grey over extended Black Leather/Race-Tex with contrast yellow The GT4 has been a staple of Porsche's line-up for almost a decade now, and the package still offers one of the most complete and well-rounded driving experiences for the money. With a massive specification, low mileage, and full-body PPF, this GT4 offers fantastic value over anything else on the market.
