May 23 (Bloomberg) -- A Porsche racing car that starred in the 1971 documentary-style film ``Le Mans'' with Steve McQueen is being offered at auction for as much as $2 million.

Bonhams & Butterfields will sell the car on Aug. 15 in Carmel Valley, California, 126 miles south of San Francisco, as part of an auction of collector cars.

Wheels associated with McQueen, a racing devotee who died of cancer in 1980, have commanded a premium. Last year, Christie's International sold a Ferrari Lusso that he owned for $2.31 million, double its presale estimate.

The Porsche was raced in 1970 in the French city of Le Mans, mounted with two cameras, to produce footage for the movie. According to the auction house, the car competed five times in the 24-hour endurance event.

Even with a presale estimate of $1.5 million to $2 million and a top speed of 200 miles per hour, it's not a particularly versatile car.

``It's a sport-racing prototype,'' said Mark Osborne, head of the U.S. motoring department at Bonhams. ``You can't do anything with it except what you would do on the track.''

A more affordable ``Le Mans'' memento: Amazon.com sells the DVD for $10.99.
