Classic Muscle Cars tried to run these 2 cars through Mecum a year or so ago as a pair and had a half million as a reserve back then. I think they bid up to the low 200's for the pair back then. Looks like the price has gone up sense then. I've seen both cars and they are very nice but they're just not worth that kind of money IMO.
You think these are pricey, check this one out....they have a 1964 1/2 Mustang convert that they want 5.5 million for!
