slightly annoyed by this
but looking forward to see more comparos between these 2.
I'm pretty sure that the M5 will have the edge on a track but than again, few owners will take their E63 or M5 on the track...
Now has the first service been performed on the F90 ? Car mileage is showing 1.943 (3"50 on the video)
There is this theory on this
thread where some people claim that the car is de-tuned before 1st service... could it be ???
