I see what you mean. The black with black piping looks right. I'm not sure what colour because my dash, door cards and carpets are blue. But the roof lining is a much lighter colour.
The chrome is in good condition. But the glass is tarnished, and the mirror unit is covered in what looks like a handpainted thick black paint.Like a poor attempt to repair it.
These are the same mirror glasses as a 107. As per standard on Merc the passenger side is convex and the drivers flat. The opposite applies to a LHD car. With a bit of research it's possible to obtain a new passenger LHD mirror which fits the RHD drivers side and you get a much better field of view.
Also got a better condition second hand offside wing mirror on the way, and me pressed metal number plates.
But not been successful so far with: -
Finding a front armrest
Finding some decent condition hubcaps
Finding a nearside electric mirror
Finding an undamaged roof lining
Swapping out the rheostat
Doing something about the right hand indicator (it wont cancel)
Still got some surface paint / rust issues to resolve and then it's on to the retrim wish list.
