Any minor part replacement is a fortune. For example, see that little tiny rectangular piece that would sit right between your shoulders if you were sitting in the seat? Its plastic, about 1" x 4", cost maybe 6 cents to make... $47 I paid!

I had a response on the rotor comment (is it just me or is it hard to type 'rotor'?) but some quick google-fu convinced me otherwise. But, seriously, why is MB/BMW so keen to put single-use rotors on their cars? They are still made of steel, right? Do they just like soaking their customers?
The oil changes, yeah - but you're talking a considerably longer interval between changes, up to 15,000 miles depending on your driving conditions.
And if you're not scared to turn wrenches, you can get OEM parts from peachparts, along with a lot of technical advice, for reasonable amounts. Benzworld.org has a fantastic DIY section that's far and away better than anything I've ever seen. They've gotten me through a fair number of service needs, and helped me to outsource one process that had me worried.
Now the factory tools (HAZET), those are expensive!
