A Porsche 911 Turbo originally owned by Steve McQueen is headed to auction. The Porsche, said to be the last special-order 911 McQueen ever bought, is an original 1976 930 finished in Slate Gray. The early production example, not unlike the very first 911 Turbo, is powered by a turbocharged 3.0-liter flat-six engine sans intercooler.

This particular 930 started like other examples of the era but along with its famous owner, it also had custom touches such as a switch to shut off the taillights in case he got a visit from the law on one of his late night runs. Other modifications included a set of wider wheels on the front and rear.

An average 1976 930 would usually set you back between $100,000 and $200,000 but due to the special nature of this car, it’s expected to go much higher and even a $1 million sale price would not be surprising. Remember, McQueen's 1970 Porsche 911S sold for $1.375 million just a few years ago.

This one will be sold by Mecum Auctions at an event running August 13-15 in Monterey, California. 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.

The Mecum auction is one of the lead-up events for the 2015 Pebble Beach Concours d’Elegance that runs the weekend starting August 15. For more our Pebble coverage, head to our dedicated hub.
