Buy a car without physically seeing it
if i had to guess that 68 is probably in the 60K + range, i see other similar cars in the 50~75K range, but whether they're moving or not i don't know.
a few interesting choices (to me at least) in that they kept the KH front discs and there's no subframe connectors. but some very nice touches of keeping the dash stock (with a factory tach!) and not "resto-modding" the interior. it's very tidy all around.
all in all, i'd consider this to be head and shoulders above anything else you've posted.
