The original poster is trying to identify sytemic failures that are unique to 1993 300E (3.2's), 1993 300E 2.8's / 1994-1995 E320's. In other words, 124.032 chassis cars.

He is looking at wagons, and the only item pointed out that is unique to this car is the water leaks at the back side windows. I don't think anyone looking at a used Mercedes wagon would ever think to look for leaking rear windows.

The systemic failure items on 124.032's, that are unique to this chassis, due to poor original designs and have been fixed with updated parts are:

1. oil leaks at head gasket
2. crumbling engine wiring harness insulation
3. OVP
4. radiator (originals have plastic necks which break

The above have failed on most cars, and if original, will certainly need updating.
