Has anyone else noticed the difference in the price of service since Mercedes-Benz took over service? I went for my two year service recently - the first at the new Mercedes Dealership. It cost me $391.42!! All I had done was change oil, oil, air and dust filters and check fluids and brakes! When I had the first service done at one year, it wasn't even 1/3 of that cost. Outrageous!
