Service and parts? Very little need for those, I'm at 100,160 and have only replaced the battery, battery ground cable (both from O'Rielly's) and the EGR valve (from German Auto Supply.com). I had the guys at a local family-owned garage do the EGR valve, one of them owns an SLK320 (with over 150,000 on it) so he knows the car very well.

I had Buckhead Imports flush the cooling system and set the engine fan down 10 degrees C ---- Who the hell needs a dealer for anything?
