Sorry, have to disagree with that.
The Merc is more than a family car with a big engine.
I have only driven one C63 and it was far more than a regular C Class with a big engine.
The E9X M3 is getting more and more like that, compared with the rawness of the E46, as is the new M5 compared to the E60 M5.
The Mercs seem to be getting more extreme while the M cars seem to be getting softer and softer. Not a good thing imho.
