2006 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
Astounding
 The M5's technology enables virtually infinite adjustments to suit the driver and the driving conditions.  It is like having a bespoke car:  the driver can adjust transmission, suspension and horsepower settings to your liking.  And there is a lot to choose from given this car's great capabilities.  It handles beautifully, with precise steering and road feel.  The M5 has ample power, with up to 500 hp.  I owned the previous generation M5, and the 2006 is a tremendous improvement in terms of both performance and comfort.  And I like the fact that the car is a "sleeper".  Unless they know their cars, most people won't know that the M5 is one of the best performing cars on the road.
