 Mechanical and electrial defects have 
kept the vehicle in the service 
department over 30 days in the first 3 
months of ownership.  The noise that 
developed recently, from somewhere in 
the dash, which started after 
replacing the starter switch, is still 
present after 2 1/2 weeks in the 
shop.  MB decided that it is a design 
problem that I have to live with.
