TBH I would have ordered PP if the car I had test driven had it on...it was on my spec list too. However, I drove a car without it in damp conditions and it pulled away from T junctions just fine. The ACC was a definite though. I have had it on a TT, and think it is brilliant. My current "other" car is a MINI Countryman Cooper S All4, and I absolutely HATE the ride quality.
Please bear in mind I'll be having it set to "comfort" mode most of the time!
