I guess. But as pointed out earlier by someone else just give it some time. They'll be almost as common as Chargers are. Then people won't be so apt to stare.
FWIW - some kid on his way to junior high was taking pictures of my black 06 mustang yesterday with his cell phone. The hype hasn't all died off yet.
A lot of mustang owners like the challenger. If I saw one I'd probably give a thumbs up.
