The Appeal

Porsche's first turbocharged road car was a sensation when it arrived in the mid-1970s, combining breathtaking, often terrifying performance with that unmistakable wide-body silhouette. Rarer still are those cars that passed through Porsche's Sonderwunsch ('special wishes') programme, where customers could commission bespoke specifications directly from the factory, making each example essentially unique.

This 1978 Flachbau is one such car, wearing a striking Sonderwunsch colour scheme inspired by the first Porsche 911/935 competition car. Purchased in 2022 from a museum in Florida, it has since benefited from considerable mechanical attention, including a comprehensive engine overhaul and extensive preventive maintenance. The vendor informs us that the car has been stored indoors throughout its life, preserving its condition and originality.
