I got my 1990 Turbo Grand Prix about 2 months ago.  But there was no Owners Manual with it or any info on it.  As far as I know, it is all stock. Basically all I know about my car is what I can see.  

Does anyone have a link or anything where I can find out what the specs on my car are.  Cause when someone asks me about my car, I would like to know what the hell I am talking about.
