One of Steve McQueen's co-stars in the 1971 documentary-style film Le Mans, a Porsche racing car, is up for action this August in Carmel Valley, California. The car is a 1969-1970 Porsche 908/2 Spyder. It features a 3.0-liter air/oil-cooled flat-8 engine rated at 350 hp @ 8500 rpm. While many of today's production cars are making that type of power, with a fiberglass body on a tubular aluminum spaceframe, the Porsche 908/2 tips the scales at just under 1,322 pounds. Power is sent to the rear wheels through a five-speed manual gearbox giving the racer a top speed of 200 mph. This particular vehicle was mounted with two cameras and raced in the French city of Le Mans to create footage for the racing film (the car is said to have competed in the event five times). The classic Porsche sounds like a ton of fun to toss around a track, but the winning bidder may have second thoughts if the car fetches anywhere near its pre-auction estimate of $2 million -- not entirely unlikely as another one of McQueen's cars, a Ferrari Lusso, grabbed $2.31 million at an auction last year.
