I did a search and I could not find any model timelines. You think someone would want to know such details. I am looking for the production years the 355. Other things like 355 models would be nice. Maybe this stuff is for paying members only. Here is a Porsche timeline for example. Paul Image Unavailable, Please Login
I think you can send them e-mails to fix these things. Here is the link below. http://en.wikipedia.org/wiki/Main_Page Paul
Could be there is some averaging in there. The 308QV might be production years versus model years. The spider versions of the 348 went into 1995. Same for the 360 maybe.
