2009 BMW M3 Sedan 4dr Sedan (4.0L 8cyl 6M)
Best sports sedan, period.
 My instructor rolled my Porsche GT3 last spring (totaled, we weren't injured!) but I don't miss it a bit after driving this car in anger.  I passed on the nav, having put up with a lousy one in previous Bimmer, and not wanting the iDrive, and don't miss either one at all.   Also got the blended cloth and leather interior and highly recommend.
