Hey guys, just fitted my new gear knob to my W203 C55, assume this would fit all other auto W203's as well. Install was pretty easy. Lift up the surround, undue the clip at the bottom of the shaft 1/4 of a turn and the knob lifts straight off. New one on, and then just remove the gaitor and fit. Massive improvement over OEM one, its heavier, and looks a lot better, the old one had worn leather over it. Bought from formymercedes.com, owner was very helpful with questions.
