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.
World class handling balance, screaming V8, great brakes, great (non run-flat!) tires, serious but comfortable interior, "billet" feel to the chassis, subtle, but head-turning looks.
Orange peel (a problem with ALL recent vintage Bimmers and the one thing Porsche clearly does better!) I figure I'll be trading in when the direct injection arrives also! Steering feel very good but just a little too light for my taste.
