This August at the Mecum Daytime Auction in Monterey you will have the chance to purchase a very special car from Steve McQueen’s personal collection. It’s a 1976 Porsche 930 Turbo Carrera and what makes it special is that it is the very last car the movie star ordered before his death in 1980.

This Porsche 930 Turbo, chassis number 9306800408, is being sold by Steve’s son Chad who apparently believes it will go for good money, as he wants to donate to portion of the proceeds from the sale to McQueen’s alma mater, the reform school Boys Republic.

“My dad had little things done to it,” Chad says. “Like on the dashboard, he had a switch put on so it would kill the rear lights in case he was being chased on Mulholland Drive.”

What you will get if you bid on this car is a Slate Gray Porsche 930 Turbo powered by a 243 horsepower non-intercooled 3.0 liter engine, no. 6860413, with Bosch K-Jetronic fuel injection. The car’s fully loaded with sunroof, dual mirrors, limited-slip differential and black sport seats. Well it was 1976, you know.

But none of that really matters to the collectors who will be eager to buy this Porsche. The fact that this 930 is the last special-ordered McQueen car is enough for them to get their checkbooks out.
