I bought a nice Z in 1982, and drive it on nice days. It has original motor, trans, rear, and most original parts, but it's missing some original items. I just was never that interested in whether it had every correct item. It's not why I bought it. And I don't really care that it will never win any shows, etc. I just enjoy it for what it is, a nice looking, nice running 302 Camaro. I have the most fun with it winding the motor in the boonies where nobody else is around.
