I've done 147 with the top down. I was driving alone on a completely deserted 4 lane road in west Texas... about the only place that I would feel safe enough. I would never have done it with a passenger or if there was traffic or houses in the area. hearing the sound of the road at 147 was a little unnerving for me... I cant help but think what would happen if I lost brakes or a tire at that speed. I know guys my age that take their srt-4's (front wheel drive turbo I4 with a neon body) or blown mustangs up to 160 all the time. I can't imagine how you would feel OK in a neon doing 160
