An ///M5. Specifically an E39. Because the E60s are still too expensive, and flappy-paddle blarg blarg blarg. So am I crazy for wanting to sell my E300 Turbodiesel, and get one of these instead?

I want one soooo bad right now...(I don't want to sell the Z4, because it's a roadster, and I would hate to lose the droptop)

Have more pictures.
