I know I had my then 11 year old '58 TR-3 up to 100mph once. It was probably on route 95 or maybe 495, a pretty quiet highway at the time. I just had to see if the old beast could still do it and it did. I also drove my friend's '71 E type up to 100 at least once on route 495 in Massachusetts. I don't think I've driven cars that fast since. Ron L
