Dynamat?
LINK
I usually have spent about $200 per car on the dynamat. I did not need to do this on my Lincoln Mark VIII and I doubt if you need to do that extensive on a MB. The coupes have all the speakers in the doors, putting dynamat behind on the door panels would be good.

But the the Coupe I havent needed it the only rattle was the plate and sponge stop that, its a wicked motor and you wouldn't know its diesel that how quite it is
