Porsche 917/30 Can Am Spyder
The Porsche 917 racing program was one of the most successful in the history of motor sport and the 1973 917/30 Can-Am Spyder represents its pinnacle. With a 1,000 hp turbocharged flat-twelve, American racing champion Mark Donohue’s 917/30 was so dominant that the Can Am Challenge Cup was disbanded and the other manufacturers withdrew due to their inability to compete.
On March 9th, 2012 this car was sold at Auction by Gooding and Company for $4.4MM which (as of this writing) makes it the most valuable Porsche ever sold at auction in the world.
