yap...the mbforum that I go to has the same complain and most of them said that the MB are really good as long as it's under manu. warranty and ext. warranty...got my warranty till 100k
so far my experience with the MB dealer are okay...they did a Service A and replace wiper blade for free...
BTW, DJ..I did some mods already on my C320
