Like Calum I'm a bit wary of reopening this debate ! But I will just say that in my experience it is very much dependent on the road , it's possible to drive for miles without it happening .
Absolutely right. And then...!
With the M3W I have learned things about the road surfaces in my area that were never previously evident from driving over them in a wide variety of cars for many years.
I look forward to driving over them again soon with the "Comfort pack", the Suplex dampers, new front tyres and zero toe out. Not that I am getting impatient, of course...
