Trailer Hitch For 1988 190e 2.3
 

Is this possible? Has anyone else done it?

I did, and when I have time I'll tell you about it, got to run...

I have time now
 

Had one mounted by a local trailer hitch place. I was wondering about a Mercedes but they had pictures of their work and had some of Mercedes and even Roles Royce. I didn't actually see them do the work but I know they took the bumber off and all the plastic trunk lining stuff out to install it. They welded a cross piece behind the bumber then cut a perfect square hole in the cladding below the bumper for the reciever. I did the lights myself. I took the left (doesn't really matter which one) tail light thing out and apart and soldiered in wires and a connector. Bought a 3 to 2 light converter and put on the mating connector then dangle the wires out the trunk to connect the trailer, it doesn't seem to bother the trunk seal. I have a 4 x 8 foot utility trailer and so far everything has acted predictably.

Thats good to hear that its possible, I would love a utility trailer to pull. Was it expensive (thanks for the info by the way)
