'97 E320 oil and filter change DIY

Hi,

I just picked up a '97 E320, and I'd like to do my own oil changes. I've come across the links below, but other than these I've yet to find any good resources for doing routine maintenance on my vehicle.

I think I can locate the oil filter cover and drain plug, but it would be nice to have an actual description of where these items are located and/or what needs to be removed to gain access. A picture or diagram would be even better. The links above are great, I just wish they were for my particular car

Information from 1-800-mercedes is that manuals for late model cars are not available; the only information is on microfiche or a very pricey subscription CD service. Is this true? Are there any other aftermarket publications that cover the 210?

Thanks for your input.
