160mph in my older modified Lexus SC400 years ago.
That was on my way from LA to Vegas, right after Barstow the highway was completely empty and I just floored it to see what it could do.
Sure enough the speedo pegged out a little over 155 and it was starting to red line. Car was running smooth though. No shakes.
I remember looking over at the joshua trees on the side of the road and they were like a blur.
Can anyone beat that?
