So regarding the chauffeur/driver issue.... I went through a ton load of material regarding who should be in the back seats and who should be in the front seats. Suffice it to say you'll be in a good place either way. First impressions, it f@#&s off. Properly. It also just glides. That air suspension is something else. Yeah it's not as driver focused as an M, fair play, but it does have a different character in Sport mode. During my research I discovered that the difference between Comfort and Sport (there's no Sport +) is the largest of any BMW, in other words the mappings between the two modes is the most extreme BMW ever put in one of their cars. So there is that.
