Would never ever go back to manual after driving my 370z 7AT, it just doesn't make sense to do 24 manoeuvre while driving fast on bends, going in, coming out.
Needs a bit of tweaking by a tuner when you do the UpRev and it's just perfect. By default, it was a bit sluggish in places.
And, ask the guys who drove my car, it's was way faster than any manual 370z, even before twin turbo.
My signature says it all
