Cool vids. Are the roads pretty choppy on the A6? Looks like you had a tough time keeping the camera steady. Then again, I wouldn't want to take a hand off the wheel for too long at 140mph either.
On a side note, I remember having a 2.5L and it taking a day and a half to get up to 140mph. The 3L pushes 150 pretty good, and 155 was about all she had. This, ofcourse, on a track.
