I drove a dark red 1988 Iroc-Z in high school. It was the greatest present a man could give to his son. She was strong, fast, powerful, loud and impressive. The 5-speed was matched beautifully to that 5.0 liter. We had a 3.73 rear end with full time posi. She got off the line like no other. I never had any issues at all with her. I damn near cried when I sold her.
Transmission- shifter felt great in the hand, and the long throws made you feel like you were turning the world upside down with all that torque.
Interior space- but it is a muscle car so no big deal.
