Strange, but true. As it worked out, we wound up scrapping the first 125 customer cars off the line anyway because fatal flaws were discovered in the main wiring harness after they were built. (I expect Delphi Packard wound up eating the entire cost). Why scrap 'em? In the case of the Mercedes M-Class (same with many vehicles), the main body wiring harness is one of the first things installed in assembly; to change it out, you have to disassemble almost the entire interior, which then damages parts, etc. You would be amazed at some of the stuff that goes on in an assembly plant...(any assembly plant).... it's a wonder that any car company ever makes any money...
