Wel, if it's just a service,I'd just take it to a Chrysler dealer. They should be able to handle that if there's no major work being done with the engine. And oh, if you're worried about getting the cheaper deal, you should probably stay away from the MB dealer altogether. LOL!
There's an old saying about "if you gotta ask, you don't wanna know".....This applies to everything MB. LOL! Good Luck Wizard!
