My M5 
2008 BMW M5 Sedan 4dr Sedan (5.0L 10cyl 7AM)
Great Car
 I've had the car for nearly a year. Great daily driver and an amazing track car. The M5 outperformes most cars and is very easy to drive.  The SMG takes time to master but once you're used to it, it's very smooth.  You can launch the car using the smg as a clutch, very easy to do. Its the easiest car to drive. Just bad gas mileage.  On the track its great. It can be driven very hard but it will overheat and the brakes will fade. Traction control cannot be totally disabled.
