Infinti G35, unless its a 2005-06 gto, then I'm not sure what'd I get. But I'd definately get a G35 coupe over a 04 pontiac gto.
The G weighs around a 100lbs less the gto and just looks incredible (especially if you do stuff to it), it has around 280-300hp and the 04 pontiac gto has 350.
G35 can sit 5
GTO can only sit 4
G35 I think handles better
G35 also is more of a luxury coupe
Now the 05-06 gto's (the ls2 models, 04 is the ls1) have 400hp and go 0-60 around 4.8 seconds and look pretty sweet with the hood scoops, IDK, its close, but i choose the g35 over the 04 gto
