Overall Rating
Alpina B12:
The Alpina B12 is a name given to high-performance luxury automobiles manufactured by German automobile manufacturer Alpina.

Production ended in 2001 when the 7 Series models were discontinued. The B12 was replaced by the B7 and the B6.
The B12 5. 0 was introduced in 1988 and was the first Alpina production automobile to use a V12 engine as its predecessor, the B11 used 3. 5 and 4. 0 L V8 engines.
