2001 BMW M5 Sedan 4dr Sedan (4.9L 8cyl 6M)
My 01 M5 - The LeMans Blue Beast.
 By far, the best 4 seat, 400 hp car in the world.  It is a beast in oxford clothes.  Never a squeak inside.  The clutch allows me to drive in very slow traffic with minimal effort and the torque allows me to just smoke the tires when I feel like it.  As far as handling, I've never had one moment where I felt like I was going to lose control.  Amazing car.
