Can anyone who really drives IS-F tell me does it handles better than E60 550 bmw or 650?!?! not M devision. F must be better than 550 or 650, and im not talking about M series... If it handles better and steering is more sharp i take it if not... what is the point?! Only for a noise??!?!!! We dont have a testdrive in Moscow. You buy it or not!
