This vintage 1975 Porsche 911S Coupe stands out as a timeless classic, with its distinctive Bitter Chocolate exterior and matching Cinnamon leatherette interior. Built during the iconic era of the air-cooled engines, this vehicle is powered by a robust 2.8-litre flat-six engine coupled with an engaging five-speed manual transmission. Now residing in Charleston, South Carolina, it retains its original status as a demonstrator unit from Irmer Porsche-Audi and has maintained excellent condition throughout its history in both the United States and Canada.
