1963 (Ford) Mercury Cougar II prototype car was a styling concept to test the waters for a Ford 2-door sporty coupe. The car borrows heavily from the 1963 Corvette...ironic since this was to be a "Corvette Killer" with 427 power. There were two Cougar II prototypes made, both of which still exist. The fastback was loaned to the Petersen Auto Museum in LA several years ago sporting a non-functional 289 engine. The roadster is still at the museum in storage in Michigan.
