In the last 15 years, MBZ has lost its way big time. From the 'flagship' of the 560SEL to the crap since then. Much of the damage is in the 'systems integration' area and caused by different subcontractors/suppliers of each individual control system--one supplier for the ABS, another for the HVAC, still another for the ASR/ETA/???--and never any thought on how to simplify things or standardize the boxes. And then there are the horrible engineerig/fabrication mistakes like the harmonic balancers (Chevy and Ford , much less any Japanese Co don't have that kind of problem) Go get in a Lexus or Infiniti and take a drive. They will even come pick up you car for service, leaving you a clean fresh 'loaner, and reutrn yours serviced, fixed, washed and cleaned.
