The other very nice thing about working on Mercedes is that the cars seem engineered to be serviced over their life. Things that need removed have actual bolts instead of the plastic “Christmas tree fasteners”. Care is given to access for common tasks. Sure, they come up with a few weak points, but routine service is satisfying (almost a joy) because you know it can go back together without rattles, loose parts, or a trip to the dealer for a few plastic BS fasteners.

MB parts are readily available and reasonably priced in general.
