It is an E320 estate model 2001. I had a quick look at the service book, I did not understand it fully, it seems during service 'A' they mostly "check and top up if necessary". Changes of oils, filters, sparks are mentioned in "yearly/miles" intervals, not falling under a service 'A' or 'B' components.

What I am trying to say is that service 'A' is pretty much meaningless unless they also change oils, filters etc for which they bill you separately!

Am I right or have I missed something?
