Lets assume for a moment the Merc is better. Not only because these two guys say so, but because the whole motor press specilized industry says so (by the way, this guy also disliked the M5 in a comparison with the Panamera).
Do you really care? Aren t you happy with the car? Would any of you make a different purchase decision? Not me. I drive what I like, not what others think may best in class.
