What kind of maintenance should I do?
 

I bought my 2000 C230K last year at 68k miles with new belt. Now I have already put 40000 miles on it without any maintenance except change oil regularly. The spark plugs are changed last month. Is there any other maintenances should I do for it? Any suggestion will appreciate.

I think they recommend that it should be serviced once every 15,000, unless you've got like aa maintenance book of somesort.

You might want to check filters, air, fuel, and cabin. Brakes good check the coolaint to make sure it still protects to a low enought temp for where u live. Other than that what dealers call regular maintenance i call a way to get people to separated from there money. No weird noises or drivig different everything should be fine u just did the plugs so i'd say ur good. But like i said changing filters never hurts no such thing as too clean at least when it comes to cars.
