I own one. hard top instead of t tops. and the 84's, like the one pictured were rated at 15.5 off the showroom floor. the 87 GNX of which 547 were built would do 12's.

bad ass car looks soo damn mean that you´d think
it drinks blood instead of gas

These were the shit when I was in high school. 12sec. off the show room floor.(what the hell were they thinking.)
