I can't believe the numbers I see here. $3,430 for the year 3 service? What could they possibly do that would cost $3,340? How could the dealer sell a 4 year maintenance package for $1425 that covers $5800 worth of maintenance? There is a big disconnect here. The $3450 figure must include things other than scheduled maintenance. I looked in the maintenance book, which is not easy to follow, especially insofar as differentiating between when to get an A or B, and I viewed the videos. Video of the A service (year one and/or 10,000 miles) reveals essentially an oil/filter change, changing the cabin air filter and checking things that I check anyway. The Service B video (year two and/or 20,000 miles) looks like Service A with the addition of spraying a lot of lube, plus the addition of changing brake fluid. At year three and/or 31,000 miles (why not make it 30,000 miles, in keeping with the first and second service?) we're back to an A or a B, hard to figure out which, with the addition of lubing the sun roof. It looks like at year 4, which has jumped to 46,500 miles, we get the A or B, again hard to figure out which, and the every 2 years brake fluid change, with additionally an air filter and new spark plugs. Since I have a FWD non AMG, I don't need some things on the list. I really want things checked, and certainly someone who works on the brand should command a higher price, but how much higher? I have a local garage that has taken me through 1 BMW, 1 MB E Class, and 2 Lexus (Lexi?) I trust them as much as I trust Mercedes. If I'm not having a problem, why not have them do an oil change, and I'm not worried about them getting the right sized O ring filter, because they'll get it at the MB parts department. I think they may be able to find the right oil also.
