it's an interesting read. i don't think the gt-r is as elegant, but it's more about pure, unbridled performance. the pink interior of that porsche is also so feminine that i don't think i could ever stomach it.
that said, the writers show their biases fairly clearly. the gtr- is definitely the better performing car, but it costs more and is designed for those wanting all-out performance. those who want a daily driver that also performs well will like the m3 more.
