I've done 160mph in a clk63 3 different times and 155+ one in a 1989 dodge colt gt.

155 in the colt was sketchy. 160 in a clk63 is seemingly effortless.

It will be fun to see how hennessey's creation does in real world testing...1/4mile, mile, at the track...etc etc. I'm as impressed with the veyron's performance driving in day to day traffic, at the track, top speed runs...etc etc. The main difference will be with the level of luxury offered by the veyron.
