Just registered here - I have a B12 5.0 Coupe. We have just completed the official first importation to the US of a B12 Coupe using all the official Alpina nomenclature in the importation process. We also went through the complete process (took 9 months and $$) to have the B12 Coupes added to the "Official List", the the rest of the importation process took another 13 months.
Specs:
B12 50. #45
It is the only Silver B12 5.0 Coupe made
It has 38,000 Km
Imported from Japan
