The Alpina B7 is made by a third party tuner, Alpina... they've been doing crazy cars for decades, us US folk just haven't been able to get at it. I got a ride in the new B7... AMAZING.
And BMW originally said all 2-doors would have been even-numbered series. Example is the Z4. Only problem was there was too much history in the M3, and the 3er is thier bread and butter. Agreeably, they didn't mess with it
