Sounds like he has inherited a car that he is not familiar with. Time will tell.
Based on his photos & description (and limited knowledge) and if it is in fact a CS (not in registry) I would guesstimate it to be about a $10K car, tops. It's apparently been sitting for a looong time, so all the running gear would have to be gone through- not to mention the cosmetic (body, paint, interior) aspects. The bench seat is kinda interesting. Definitely needs a Marti report for verification.
I wish him well, and hope the car finds a good home - BUT:
$2,000 eng O/H
1,200 C-4 O/H
8,000 Paint & body
1,000 Interior
$12,200 + Purchase price + Unknowns (fuel tank, alternator/VR, Carb, Brakes, etc.)
That puts total cost at the high end of the $$ spectrum for a driver.
