Our gripes with the M56's interior are heavily outweighed by its positives. It doesn't have as much rear leg, head, or hip room as the BMW, but it's a much better designed interior. Every swath of interior space was made to flow with the one that comes before and after it. Everything is flowing. It feels almost like a concept car. The seats are comfortable and firm, the materials that are supposed to be soft to the the touch are actually that; everything is just very sumptuous, but not to the point of being overly elegant. Dudes should have no problem pushing one of these.
