Hi I have a right hand (drivers door) exterior mirror from my UK 1998 SL. The triangular piece unscrews and then its the same as a C or E class mirror of that age, infact it has 210 part numbers on it. Its heated with memory, dimming function, is green/black and in excellent condition. Also, I have the dimming mirror glass which is around £150 to buy from MB. You need a dimming inside mirror to make the outside dimming work, and there is 2 wires that need to run from the inside mirror to the outside. (I updated to newer mirrors) - Im in Lightwater, Surrey I want £50 for the mirror itself,£50 for the glass, or £75 for both.
