I've got 105K on my '01 C320 and was wondering what type of engine service should I be doing at this interval?

Spark plugs? Transmission oil? Etc.

Thanks in advance.

 

it all depends on the vehicle maintenance history escpecially if it not kept per mb specs, have these ever been done, plugs, fuel filter, air filter, if the trans fluid never been changed-then don't it going to start to leak.
