£4,220 above the median asking price
Compared with 7 other Porsche 718 Cayman S for sale on Vertar (2016 to 2019). Median £38,780.
The 718 Cayman S marked Porsche's switch to turbocharged flat-four power, with a 2.5-litre engine in place of the old naturally aspirated six. This 2018 car pairs it with the seven-speed PDK gearbox and rear-wheel drive, and the page quotes 350 bhp.
It is finished in GT Silver over black leather, and the specification is well chosen for a road car: Porsche Sports Exhaust, PASM adaptive suspension, Sport Chrono-style driving mode button, heated sports seats and steering wheel, PCM 4 navigation with Apple CarPlay, and 20-inch wheels.
It has covered 41,000 miles and is described as having a full service history. The MOT runs to June 2027.
