I think they are worth way more to a collector or museum, exactly where they (supposedly?) are heading.
As others have stated, if it weren't for the VIN numbers, they are worth somewhere in the $25k - $30k range fully restored (each)
The xtra value of being the #1 or #2 cars is WELL UNDER what hyped in that show. (IMHO 50% max increase)
The cost of the restorations will far out-value the cars themselves.
Whomever bought those cars for north of $600k has way more money than they could ever use.
My latest thought is "if" they are going to ND as stated, OIL money from fracking has got to be involved. They will never recoup (pun intended) that investment.
I used to be indecisive. Now I'm not sure.
