If you bring your own mobile1 to the dealer a single wrench service is like 70 bucks and they check all the other stuff on the list for you as well. As others have said the damper that the dealer tries to sell better have gold plating because it is a huge rip off. Even at the MB dealer its only 90 bucks. Online 20-40 easy and not hard to put in. I have replaced one myself and had the dealer do another one (think it was 30$ charge for install). If you don't want to do it yourself just bring all the supplies to the dealer and you can save that way. Still not "cheap" but much more bearable.
