RE: Wiring Harness Replacement....
No the W123's are made of regular plastic sheathed wiring just like current american ones. Mercedes got all "Green Earth" on us and decided that an abandoned Mercedes left to absorb back into our planet had to have wires that became brittle and decomposed so it could become one with nature once again..... although a 3,500 pound car with no wiring would just sit there for the next 100 years. Go figure!
I mess with the wiring all the time with my 81 240D (Window switches, glow plugs) and I've NEVER had the stuff just fall apart like my 95 E300D, a car 14 years newer. For all the tremendous feats of engineering that Mercedes has provided us, this has got to be their most embarrassing "skeleton in their closet"
Sure wish I could get Andy Rooney to do a piece on this! [:D]
KC in reply to your question, I believe that heat is a principal ingredient to the degradation of the harness, so shelf life is probably not a real issue. Besides, for as many people that are having to replace their harness Mercedes is probably working round the clock manufacturing them so I'm pretty sure they don't sit around long. [:D]

Yea these cars will last a million miles but what with terrorists, natural disasters and the H1N1 swine flu pandemic... God help us there's anyone left here to drive them.
