The great thing about the M5 is that it is essentially a very very comfortable car !
So the trip there and back was waaay better, and less stressful.
I know definitavely that the cossie is faster in a straight line that the M5 now. My mates M3 will keep with the M5, and My cossie was quite a bit quicker than his M3 in a straight line!
Round the track, both cars achieved about the same time. This I believe to be down to the extra speed in between the bends! Not sure though.
Cossie suspension was better than expected, and yokohama tyres very very very ver grippy!
Still life in the old dog yet, so as to speak!
