2005 BMW 6 Series Coupe 645Ci 2dr Coupe (4.4L 8cyl 6M)
Best BMW I have ever driven or owned
 I have owned BMWs since 1977 (3, 5 & 7 series) as well as two Porsche 911s.  The 645 is the absolute best, hands down - performance, drive, feel, style (interior and exterior).  Recommend sport and premium pkgs.  Sport drive is amazing.  The 645 is the perfect balance of performance and comfort.  The sound of the engine is awsome.  And I-drive is very easy to understand.
