Haha, I for one don't care much about rarity or anything like that. Up in NOVA you're not driving anything rare unless it's some limited run Ferrari or Lambo.
I can definitely see the Z being pretty rare in Radford... when I used to go to visit when I still had mine I never saw another 370 save for one or two at the dealership in Christiansburg, but that's it. Mustangs were pretty popular down there. Less so up here around NOVA where the "it" cars are the 911 and 3 Series. I only see one or two '11+ 5.0s a day.
But again, I care about the driving experience. I'm not worried about being seen in something that you don't see very often. Unless you're going to spend big bucks that's kind of a lost cause up here anyways.
