how much do 240z cost
 

how much would a 240z cost with not much rust and driveable?

well, where do you live? how much is "not much" rust? Do you mean like little bubbles in the paint, small chips, some spots?

IE, most of the rusted parts have fallen off :- )

its called WEIGHT reduction, man!! (j/k)

Look in the for sale section. I have a 73 that's completely rust free and should stay that way (at least the frame) for a while since it's been zinc chromated. It depends what kind of condition you want it in. Completely restored, upwards from $8K (at least) all the way to high numbers. I'm letting my completely restored (stripped and then restored) 240z go for $6K or maybe even less.

WHEN YOU SAY COMPLETELY RESTORED . THIS MEANS ALL STOCK AS ORIGIONAL MATCHING NUMBERS ORIGIONAL BOLTS OR NEW NISSAN FACTORY BOLTS EVERYTHING , INCLUDING PAINT . NEW PAINT IS ALLOWED IF ORIGIONAL COLOR. INTERIOR AS WELL. STEEL WHEELS WITH HUBCAPS. EVERY THING AS CLEAN AND AS IT WAS ORIGIONALY DELIVERED . If is what you are selling for 6k this is about 1/3 what Iit's worth. But that is what is a complete restoration is.
