I had a similar problem with a Toms River Dealership, (since then, Mercedes has pulled their dealership), because of wind noise in the drivers door. Because of their inability to resolve the problem, I contacted MBUSA by phone. After giving all the information, the district rep. called my home the NEXT day and made arrangements to meet at the dealership. My problem was solved that NEXT day!!!! However, I am interested as to the excuses given for the service taken so long?
