Remember that Alpina is classified as a builder, not a tuner, in Germany. What they do is basically get a complete, albeit not assembled, BMW from Munich then change up just about everything. The motor, body, suspension and interior are all upgraded all at once at their factory. So, with Alpina, it's a full custom treatment on your car. Hence the 'B' designators. Not sure why they picked the letter B, but a BMW 3,5,6,7 etc. becomes an Alpina B3, B5, B6, B7, etc as it's a totally different car at that point. And while I'm not a huge fan of the wolverine wheels, their multi-spoke wheel with the integral valve stem, as seen on the late-model Alpina B7, is absolutely stunning.
