Mike is correct BUT....
It's just a small part of the story....
Chassis #CSX2287 was one of only 6 Shelby Daytona coupes built to run for the world sports car championship in 1965…. Which they won. This is the only time an American team has done this, even to this day.
Anyway, after Shelby won the championship the cars were useless as the GT40 program was on a roll by then (different story). So in comes a call from Goodyear. Seems Breedlove was trying to set a land speed record but needed to do some work on the car back in California. This would have allowed Art Arfons to use the salt (read that as Firestone) if Breedlove wasn’t Sooooo, Goodyear asked Shelby if he’s got anything they can run at Bonneville? Just so happened he’s got this old used up POS race car.
So Breedlove, Tatroe, & (get this) Shelby mechanic Greatorex took turns setting endurance records (see above) until the “Spirit of America” returned to set the land speed record.
Oh, and the last time one these cars sold it went for..... over 8.5 million! So much for old race cars being put out to pasture.
