Datsun 260z. My dad owns one and used to race it all the time (heh, not legally though), however for a while it's been taken apart (for some reason I don't know why) and he's never had time to finish putting it back together. I'm hoping I can work with him sometime to put it back together, he says that it's an amazing car, and certainly seems so. I wouldn't mind owning one, and a Datsun 240z would also be fine.
Seems to be alot of Datsun lovers in this thread, which is great.
