I'm on the hater side. I don't want to feel every crack in the road. Uneven surfaces bounce the occupants side-side. I have the performance seats - they don't make a difference. I've driven it with the 19" and 21" wheels - no difference. I drove a P85 loaner yesterday and it had a much nicer, smooth ride - and the handling didn't feel a lot different. I owned an S85 for 18 months before I bought this, it had a very nice ride. If I wanted a track car I would have bought one. This is a performance sedan. So why does this version have such a harsh ride? The weight and placement of the motors?
