A 1970 Porsche 917K was on display at the Goodwin Pavilion in Pebble Beach, Monterey, Wednesday, with the car up for auction and expected to fetch somewhere between $13 to $16 million (€11 to €14 million).

Goodwin Company specialist Hans Wurst said that although all 917 Porsches were "valuable inherently", the history of the particular model "boosts its value quite significantly over other examples."

The vehicle was owned by famed Grand Prix racer Jo Siffert, who loaned it to be featured in the film Le Mans when it was driven by the American actor Steve McQueen.
