...I'm sure when it was brand new that the ride was pretty smooth but with the newer seats and electronic suspension components in the performance cars, there will be a noticeable difference. Mine is a little stiff when hitting bumps in the road or uneven roads but on good road, it is very smooth and quiet. I'm sure if my seats were repadded to new and I replaced all suspension components there would be a noticeable difference but for now, it is better than my '05 Altima SER.
