I drove an 02 M5 a few years ago and have to say that it had one of the best clutches that I had ever used. I loved it and had no issue at all getting used to it within a shift or two, I was focusing on how hard I could push the car without getting pulled over 😛
The one experience that shocked me with it, that I tell everyone, occurred when we took it on the highway. The sales lady told me that we were cruising at 60 and so I should drop it in second gear I believe it was and floor it. I did that... only a moment later a beeping sound came on, with a confused look I asked her what that was - she simply told me that we were already doing 100 :shocked:
I realize that 100mph might not be that big of a deal, but it seemed like a second or two at most while it was accelerating. I'd consider the M5 to be a more practical version of the Porsche 911.
