Just had a 70 240 Z given to me by my father inlaw, he baught it new when he was stationed in okinawa where he was flying transport planes out of veitnam,he had it shipped home, it was his daily driver.It's in pretty good shape I think, been painted a couple of times never a rust problem he just wanted to change the color.The motor is all there and original, frame seames to be rust free, little rust on driver floor , interior has seen better days . thinking about doing a rebuild strip it down and put it back together replacing cosmetec and mecanical parts as needed, not a (as new )restore but a really clean good drivng car vin # is 5491 so I guess that makes it a fairly early car

Welcome to the club. You came to the right place if you are interested in learning all you can about the 240. Sounds like you got one of the early ones and at the right price. I don't think there are too many 1 owner 70's out there any more. Happy hunting.
