1964 Porsche 904 GTS
- Engine
- Six-cylinder twin-cam (currently fitted; original was a four-cam flat-four)

Porsche 904 GTS chassis 904-062, completed on 25 March 1964, is an early example of the landmark mid-engined fibreglass-bodied competition car whose lineage led directly to the 917. Delivered new to a French privateer in Marseille, it was actively campaigned in hillclimbs and rallies through 1965–66 before a frontal accident led to a series of ownership changes. A comprehensive restoration was carried out by Heinz Kurek between 1975 and 1979, after which the car passed through several further hands before entering the Petitjean collection in 1993, where it has been on static display since. Currently fitted with a six-cylinder engine, it is not in running condition and will require mechanical recommissioning.
