Why it matters
The 964 Turbo 3.6 S Flachbau revived the flat-nose look of the earlier 930 programme on the final, 3.6-litre version of the 964 Turbo. Porsche Exclusive built only 76, making it one of the rarest air-cooled Turbo variants.

The cars used the 3.6-litre single-turbo M64/50S engine with the X88 performance package, rated at 385 bhp in the auction catalogue. In total 76 were built, of which 39 were US-specification cars.
