These cars, near as I can tell, rarely if ever leak up front with head gasket probs; however, front seals are extremely common. As a matter of fact, as I understand it MBZ has recently come up with a new sealant that's supposed to be very effective-I'd have my independent check it out, or get your second opinion from a qualified dealer.
Clean it up as best you can; a clean motor makes it easy to diagnose problems accurately.
