Hi everyone, hope you guys are doing fine. I am new with Z's and don't know anything about it and need your help. I like older BMW's and last year I bought a 77 280z yellow it was sitting in the garage since 07 paid $1200 brought it home, changed the gas tank, cat/muffler, EGR, wire's, good tires, brakes all around, all hoses, detail now runs like a bullet. I drive ones a month and every time I am on the FWY three or four drivers following me. Now, I like Z's more then a BMW. I met a guy he told me to get 70-72 that will bring more money if I want to sale it. Well, now I bought a 1970 Arizona vehicle for 7K no rust first owner. Anyways, my question is to you guys. The VIN. # end's 300932 does it mean anything? Someone told me over the phone you got a gold. He knows Datsun very well. What makes 932 so special. Any advise will be greatly appuciated. Thank you
