There MR and they were desingend to (and do) run with the Ferrari 246 and the Porsche 911's of their day the only place the Europeans got the Pontiac was in top speed, and not even by that much. My grandman told me today that when he (my grandfather) got the 88, he got my grandma in the car and told her to watch the speedometer so he could keep his eyes on the road during a max speed run on the freeway. My grandma says they reached a tad over 140 (MPH), which my grandma doesn't lie when it comes to cars.
