If the guy can't tell that this car is no Chrysler, perhaps you should not be going to him at all. I lived in the small-ish town of Cumming, GA and went looking for someone to bleed brakes on the Crossfire and change the pads. I noticed that "Glovers Garage" was staffed by some middle-aged brothers and their sons, and an SLK320 was often in the parking lot. I stopped in and told the guy what I wanted done. His response, "Sure, we can do that. Now, ya know, this car is a Mercedes..." I knew right away I'd found the right shop. Find one like that.

The '320 was this particular guys' wife's daily driver, he'd already learned about the RCM issue and the "sticky key" problem........... Glovers is not a "German Auto SHop" but may as well have been.
