I just got my Konis installed about ten days ago on my W202 C Class. Between them and my new H&R springs, I couldn't ask for a better ride. I had a sports car before and was unfavorable of the Mercedes' boat like handling. It now handles like a sports car. And the firmness is adjustable (I now have mine set at full firmness all around after riding a week with soft in front, medium in back). I highly recommend them, they change your ride a lot.
