The Mustang That Never Was... Almost!

Behold the 1964 1/2 Mustang 'Shorty,' a two-seater prototype with a Mustang’s 260 V-8 bored out to 302 cubic inches, equipped with a three carburetor setup and all the accoutrements of a muscle car before there were muscle cars. Did I mention it was all fiberglass, and fully 16 inches shorter than the original Mustang?
  Destined for the crusher, the designer actually stole the car and walled it up in a warehouse to preserve it. It gets complicated after that. The designer abandoned it, Ford reported it stolen and got the insurance money, Aetna (the insurance company) got the re-discovered car and sold it to a car enthusiast for pennies on the dollar.
  The car enthusiast restored the Shorty and put it up for auction at Amelia Island. With a full Ford pedigree, it sold for $551,000!
