Ha! Oh well, can't be cool with someone who doesn't know what a car is worth in the first place so that he has to post pictures on a forum and ask. Obviously you don't know what you're talking about. Please buy this "barn find" its really not that desirable at all. Thats like buying a fat chick bug. Low miles or not its still a fat chick. Only thing it has going for it is the fact its got a callaway kit (that also has missing pieces). I can find 1978-81 roccos all day.
Your NADA.
