Cool, and with only 68,000 miles. That's less than 1,400 a year. Barely broken in.
The problem with something like this is that while indisputably it's worth a fortune, if it were mine I'd starve to death before I'd sell it.
There is another similar story of the first Mustang that was actually built, which secretly toured major Ford dealerships. The car belonged to the Ford Motor Co but - and I'm going from memory here - when it was at a dealership somewhere in Canada an over zealous salesman sold it! He sold it to an airline pilot who, when approached by Ford to get the car back, was reluctant to part with it. Ford got it back, but it cost a lot of money, as well as a replacement Mustang!
