Let's stick to what was in production at the time.
What car got you going in middle school? Corvette? Ferrari? Mustang Cobra II....?
For me, my dream car being produced as a kid was the (brand new!) Dodge Viper. I also fancied the Corvette ZR-1 (C4, mercury marine version).
I had a poster of a Vector W2 up; but I'm not sure if that ever reached production.
