I spoke to the owner, who quoted me $2000. Since the ad you posted notes one Virginian is $800 and the other is $1200, perhaps he meant $2000 for both, but it didn't sound that way.
I also asked about the Triumph TR6, and was quoted $1500. It is a good project because the body is rust free, but of course is of no interest to KF fans.
Most of these cars are very good deals for anyone doing a restoration project. These Virginians are in much better shape then the field car I bought in Minnesota for $600.
One should suspend the whole "what will the car's value be afterwards" and just buy them and enjoy restoring one of the iconic cars ever made. It will cost more to restore but who cares?
