Well I can tell you after test driving the o4 (both the 6sp and the auto) I love the car excellent performance and handling and the interior is to die for,the few styling changes for the 05 are nice and should be useable on the 04's.I tried to get my soninlaws interest up but he's got this bimmer crap in his head (no accounting for taste) but i can see a GTO in my near future I JUST LOVE THIS CAR.
