You wait a couple of decades for one BMW M7 to come along, and life brings you two. Well, not quite: neither BMW's own M760i or this, the 2017 Alpina B7, is officially an M car, but then neither would you really want them to be. Go too far down that track and you end up sacrificing luxury in the name of raw performance, and that's entirely at odds with the 7 Series raison d'être. Does that make the Alpina B7 a plutocrat's sports pretender? No, no it does not.
