I am guessing these were 05/06 cars?
I could see it for originals, but only if they were legit and not kit cars.
For the 05/06 cars, you have to realize those cars have an international interest. The guy that designed the Gran Tourismo games for instance ranks it in his top 5 cars of all time. Ford wanted an international appeal when they built these, to try to bring back some of the LeMans marketing fame basically as they were pushing into a global company in the early 2000's. Ford doesn't do ANYTHING unless they think it will sell more mundane, ignorable family trucksters, like the Taurus or the army of jellybean crossovers now. Once they got their acclaim, YOINK, no more for a while.
So a million bucks for a clean original 05 or 06 is a possibility with todays international rich guys bidding. We are living in the closest thing to the mid 90's "collector" price explosion as we have had since that time. Car guys won't understand the idea of spending a million dollars on a car to never turn the key on it, but car guys don't buy things like this for that money, bankers do. The million dollar car was loaded into an 18 wheeler enclosed trailer to usher it off to a climate controlled collection warehouse building I am sure, to have the staff dust it once a week. The collection makes a good ice breaker when talking to investment bankers I am sure.
