I have an Ultra Yellow 350Z........so you know what color I will suggest!!!!! Go for it and dare to be different!!!!!

I like the red myself.  Yellow as a 2nd choice, but not worth the extra $500 in my opinion.  White is a definate no no.  A neuteral color that people won't easily see and lane change into you.  That's why I won't take white, silver, grey, or black.  Camoflages with the driving environment and some idiot will pull into you.

Of course, you could always stomp it when that's about to happen, if no one's in front of you.  That's why the rear visibility isn't that big a deal.  Who the heck is going to be looking back in these car?  hehe.

But you better hope limp mode hasn't kicked in.  As soon a the first lawsuit comes up over it being a safety issue it will probably come stock with the oil cooler.
