Not sure I like the fact Alpina went with the Non M-Sport front bumper.
It just loses so much of that aggressive sports car look factor but i guess they wanted the subtle sedan look.
The M6 front bumper and intakes sweet, the M-Sport not so bad either but the non-M or B6, mmm not so pretty.
Aside from the fact it is B6 and that just sounds extremely rare I would take the M6 over it for all other reasons.
