Outside of the general mileage maintenance required on a mercedes, could someone recommend an auto service facility that could take care of the additonal, minor, maintenance that is required (e.g. brake flush, engine air filter change, etc.)? It's been rather difficult searching for a facility that caters to foreign vehicle maintenance, outside of getting my oil changed. I don't think it's necessary to go to the dealership, wasting money, on a service that could be dealt with elsewhere. Also, the filter change that accompanies the general mileage maintanance, would this happen to be separate from the engine air filter change?
