For anyone reading this....
There are basically 2...no, let's make that 3....types of door mirrors for the ForFour.
1/ Manual
2/ Electric
3/ Electric + heated
(I don't think they did the manual ones with heated mirrors in them...but I could be wrong)
The door mirror assembly is made up of quite a few components, but the 5 major parts are....
(1) the door mounting 'block' or base (usually painted to match the door panel)
(2) the main body/shell assembly (usually black)
(3) the top 'cover' for the main body (often colour coded to match the door panels)
(4) the LED indicator lense unit
(5) the mirror glass.
Yes there are also adjuster knob + cables and other bits if it's manual, or the stator motor and
loom if it's an electric, but these are the 'variables' from the main parts of the assembly.
Any replacement parts for the main assembly (when obtainable) from MB, would have been in
plain ol' black......ready to be painted if necessary.
