Little beats the Porsche 917 when it comes to dead sexy and dangerous racing machines. The 917 was first rolled out at the 1969 Geneva Auto Show, and followed up the 908 with more power thanks to four more cylinders than the previous eight. Early reports at handling were scary, with the car evidently moving about the track at will once it got into the 200 mph zone. None of this stopped the 917 and its drivers from winning races. This particular 1971 version will be up on the Amelia Island RM Auction block March 10, and is expected to fetch up to a million dollars.
