1970 Porsche 917 – $14 Million

The iconic Porsche 917 was a prototype racing car that gave the car company its two Le Mans 24 Hours race wins in 1970 and 1971. The famous car made its debut on March 12, 1969, at the Geneva Motor Show. Porsche built 25 of these cars with only one goal in mind—win the 24 Hours of Le Mans. Under the leadership of Ferdinand Piech and Helmuth Bott, the 917 was designed by Hans Mezger. The 917 engine was considered, even to this day, the greatest twelve-cylinder engine created. The body weight of the 917 is light as a feather, weighing only about 174 pounds. Its performance was increased to a substantial degree with its engine components made out of magnesium, titanium, and other lightweight alloys.

The 917 was famously driven by Steve McQueen and was featured in the documentary film Le Mans. In 2017, that very car was sold at an auction for $14 million—a record price for Porsche.
