Why it matters

917-024 links three stories: Porsche's 1970 Le Mans test programme, Jo Siffert's career, and Steve McQueen's film Le Mans, in which it served as a camera car and appears as the Gulf 917 that wins the race. Its sale for $14,080,000 in 2017 made it the most expensive Porsche sold at auction at the time.

History

Brian Redman and Mike Hailwood drove 917-024 for the J.W. Automotive-Gulf team at the 1970 Le Mans test, where Redman set the fastest times. After further testing at the Nürburgring and Ehra-Lessien it was sold to Porsche works driver Jo Siffert, who leased it to Solar Productions for Le Mans, where it was used as a camera car and appears as the winning Gulf 917.

Siffert kept the car until his death, and it led his funeral procession. It was then sold to a collector in Paris and stayed hidden for about 25 years until it resurfaced in 2001, still in Gulf JWA livery. After a restoration by Graber Sportgarage in Switzerland completed in 2017, Gooding & Company sold it at Pebble Beach in August 2017 for $14,080,000; it is in a private collection.
