I have personally driven about 140 in a 66 pontiac bonneville, fun slowing down with drum brakes, the speedo goes to 120 and the needle went past that and hit the dash and couldn't go any further. It has a very nice 389 big block in it with something like 2.90 gears, not very fast off the line but it sure flies, 3 spd automatic, it will go over 90 in second gear. I have been 160 mph in my buddies car. I am starting to slow down in my old age and I am only 32, to many time crashing and burning. I had all of the fast atv's and dirt bikes, ds 650 fourwheeler, ktm 380 2 stroke bike, and a banshee, I stay with my 4x4 quads now.
