To be honest, probably not much. Just judging by the pictures, it looks like it's in pretty fair condition, body wise. But it looks like the top has damage, the interior is shot and most likely, given where it's sitting (for 20 years), the frame is probably shot in the middle area (a bad spot for '60s Galaxies) and the floorboards and maybe the trunk area are probably bad now. If the engine isn't running, then you can't confirm if the tranny is still any good. Without a good going over to check the areas mentioned...maybe $500-$1000 depending on how good all the trim and hard to find parts are. If the floorboards and frame are ok, and you could get the engine running, maybe $1500+.
