Whats a 72 Grande Coupe Worth?
 

It's got some mechanical issues (drives, but leaks some coolant, low oil pressure, etc). But interior is 90% original. Paint is OK, but there's some rust under it here and there and was just painted over. Original engine from what I can tell (302) with 3 speed auto (ouch). Nada says 5775, but let's be honest, you rarely get that much. What do you guys think?
