Although I am less enamored with the new look from straight on in the front (mid lip thing sticks out further than the lower lip?), all in all I like all the cosmetic changes (variant wing, new wheels, kit, tinted lenses, seats).
But... the only real performance upgrade (alleged aero improvements notwithstanding -- lets see it in a wind tunnel...) is the final gear ratio.
Otherwise there is NOTHING new about this car.
My only fear is that this IS the Z35 with a snazzier body kit and nicer seats... again, see further the "new" Q60, which is really only a slight update of the G37..
