John -
One last tip re:trans fluid. You can get the OEM fluid (MB packaging) from *************** or fastlane (this site). Considerably less than dealer.
Part No. 001 989 21 03 10. ($14.84/l last time I bought). This is the original 5sp fluid. However, some posters have said that MB is also approving the new 7sp fluid for use in the older transmissions. I haven't confirmed that but price is about half(?) of old fluid. I just did mine and decided that the extra $60 (for the older fluid) spread over 80,000 miles wasn't much of a hit.
Good luck with your 'new' car.
