I have gotten my crossfire up to 220 km/h (137 mph) a few weeks ago. It felt extremely steady and as if I was floating on air...haha.

I drove my dad's E55 AMG on monday night, and hit 260 km/h at which stage the car wouldn't go any faster as it reach the limiter (even though it is supposed to be limited to 250 km/h...just indicates the accuracy of a speedo) with my dad sitting next to me. I didn't even know we where going sooo fast...can't feel speed in a car like that. My 2 friends, who sitting in the back, pointed it out to me...Haha.
