I recently came across the GM vehicle inquiry system printout that I got several years back for my 98 Trans Am. Started to wonder why I never got one for my 87 GN, then I seemed to remember that the service dept guy told me that it wasn't in there due to the age/year of car. Anyone familiar with the GM VIS can tell me if I am remembering right? It would be a nice way to start to figure out what my GN was born with. If this isn't possible, my next step will probably be starting with GM media archives.
