Personally, I'm not sold on ALPINA and this new B7. There are many reasons I say that:
1) ALPINA (for me) is not a brand that is not really affiliated with the BMW Group. In fact, I feel like the relationship between ALPINA and BMW would be like the relationship between BRABUS and Mercedes Benz.
That and it is not authentic unlike M Gmbh (which is the one and only performance arm of BMW Group)
2) Wheels look like sh*t.
3) In the F01/F02, the performance variant was NOT the Alpina B7 BUT it was the 760Li with M-Sport Package. The 760Li M-Sport was the flagship variant of the F01/F02
4) ALPINA looks like some luxury pimpmobile. I'm willing to believe that the upcoming M760Li will be a more authentic and more polished interpretation of the G11/G12 7 series.
Just saying
