A couple of more thoughts: I really have begun to wonder how old those photos are. I see an intact car with the under-body shots showing none of the really significant rust issues he is describing. All I see is surface rust on the upper side of the trunk floor and the 2nd shot shows the tops of the rear shock mount points and they look fine there. This car really needs to be seen to see it's real current condition.
The other thought is that if it had been left with it's original drivetrain (as a Sprint model) the value of the car in good condition would have been considerably higher. The previous owners did no one a favor there.
