The technical aspect of this post is dominated by the stupidity of the author's statistical conclusion: MB are crap. Lots of case studies here I can tell.
Well, from vast experience, I can confirm that there are crappy cars from every brand and from all that experience the single most common problem of all those cars is their owners.
Writing "MBs are crap" on an MB board has to be the eqivalent to yelling fire in a crowded theatre. If I had the ax this thread would be history.
