Whoa! What? Nissan makes more than one shade of gray?! Now, why would a car manufacturer do THAT!?
OK, in all seriousness, the Z is the first car I've seen that looks good in every color offered. You just can't go wrong. Get the color that appeals to you most.
Oh, yes. I almost forgot...PW is clearly the nicest shade of gray they offer.
