I am looking for trim piece that runs the lenngth of the door, the one underneath the door handle. Sadly coupes are difficult to find, and the yards only have sedans or wagons.

Also looking for the driver side inside door lock.

Those parts are readily available from the dealer still at reasonable prices. The door lock piece is the same as on SL's I do believe, at least that's what I was told at the dealer parts dept. when I bought mine, about $5, can't remember what the price was for the door molding, I believe it was in the less than $20 range.

I just ordered up the door molding, it was $45 wholesale. As for the door lock, the mercedes parts counter couldn't find it on the diagram, would anyone have the part number?
