I'd rather own the Batmobile.
It's worth a small fortune - i think the last sale on it was 4.2 million at BJ last year.
Not as cool as the FGT, or as great driving a car, but I could buy 20 FGT's if I sell the Batmobile!
Don't confuse value with price. The BJ auction of the guy buying it was between two people that really, really ,wanted it. That set the price. Try to sell it on an open market now and it might not get the price of a delivery miles Heritage GT.
