Recently a neighbor that had two Lexus bought a new Mercedes S-Class. Based on our experience with Mercedes dealer service my wife said; "I bet that as soon as they take that MB for its first service, they will go back to the Lexus dealer and beg to have their old GS400 back!". Sad but true. I agree with the independent Mercedes Shop comments. I service my MBs through one that has earned my trust and don't even care about the dealer(unless car needs some expensive warranty work).
