I just feel sorry for people who rely on dealerships for their paid service. I only use them for warranty work and on the past few new cars I have bought they have done the maintenance because it was under the paid program MB offered for the first 4 years/50K miles. For my older cars I usually do the work myself or have a good indy or two I know help out. The dealer has good people in the parts department but the service department sucks, pure and simple. I won't name them but they are the only MB dealers in NH and own both dealerships in the state
