If you go to the library they have these books called periodical something...it's like a index of all the information about a subject that has appeared. There's like a million books, each book spans like 1 year. Well, you can look up Nissan 300Zx and find a list of artciles in magz or newspapers. Assuming that the first artcile on the Z started in ...oh...1989...i'd look up 300Zx from 89 to about 97...they don;t really include info on magz like Super street. That's one way you can check.
