Z4 is a BMW so you have to stop indicating direction turns and drive like an **** using the hard shoulder of the motorway etc....

350z nice car but having driven one i couldn't drive it everyday its just hard work (would make a great weekend car)

RX8 sounds like its got manic hampsters in where the engine should be, you have to rev the nuts off it to have any fun....give me a 3.2 anyday
