Nice review . Now the wait to get mine is even harder
But at least I had a fully broken in one over the weekend here in Munich and I can tell you an unlimited M5 will scratch the 200 mark.
I agree the features missing are high beam assist (would be great if indeed they could be coded) and auto handbrake .
It also turns out the ///M Performance Carbon Interior trim has just been released. It should come in this Friday and I'll hopefully get it installed on Tuesday (day after taking delivery) ...
