It’s no secret that Steve McQueen loved his automobiles. The late actor is known to have owned some of the coolest cars around. A Ferrari 275GTB, Jaguar XKSS, even a Hudson Wasp graced McQueen’s driveway at one time or another. Now, one of the very last cars he ever owned will sell at Mecum Auctions this summer.Steve McQueen’s special order 1976 Porsche 930 Turbo will no doubt be a highlight of the 2015 Monterey Car Week. The Porsche was ordered personally by McQueen in a very rare slate grey. He specifically wanted the stealth color for late night canyon runs. McQueen even went as far as to have a toggle switched mounted on the dashboard to cut the power to his rear lights. This way the police would have trouble reading his license plate.A portion of the proceeds will be donated to benefit The Boys Republic, a non-profit treatment community for troubled youngsters in Chino Hills, California. McQueen credited The Boys Republic for turning his life around.
