10 year old C280. Never changed fuel filter. 30 year old Chevy, never changed fuel filter. I don't think MB's need much attention. Of course change oil/filter every 6k miles. Car seems to work fine. The hardest use an MB can get is to let the kids drive one. Then you might want to check things out. My experience is that the MB is pretty maintenance free.What say you? Of course if you service your car at a dealer, these items will need to be replaced.and you pay a lot for this.
