Just for reference, my 83 300D Turbo had a remote passenger side mirror adjusting switch located on the center console just in front of the speaker (front/rear) switch. But the drivers side was manually operated. My current 82 model has both mirrors mannually operated. I do miss the remote switch for the passenger side, but hey, I just deal with it because it's a Mercedes. My biggest problem is that I cannot fully adjust the drivers side mirror.. stuck/hard to push etc... so I still have a "blind spot" on that side and have to turn my head to make sure no one is next to me in the other lane etc.
