I never really push my GT that hard... but the first run I got on the autobahn in the ol M5 ran me just up to about 202.. or so... After I looked down at the s/o I nearly s**t myself... it really never felt like I was going that fast just staring out ahead... and being an American, and not used to that speed, kinda makes ya wonder... (what if I get wheel jump...) or something of the sort... and really puckers your A**hole... but it was a great experience I will never do again... like carrier take-offs.... heh.
