 Most of the reviews cover the important tech issues. I love my car but from day one I assumed that the rough and relatively noisy ride was related to the "sport type tuning" of the car's suspension - and I would just have to live with it. How wrong I was. This was the only thing about the car I did not truly enjoy - it was very noisy - road noise that was magnified by any road imperfections.  Living in NY, I knew I had to replace the stock 17" Summer Tires (potenza) with an all weather tire. This weekend (October 2010) I put on a set of Conti Extreme Contact DSW and wow, what a difference. The car was transformed - it is now composed and a pleasure at any speed and road surface.
