Love both of them.
The '11 Mustang in in a different league, as far as interior, and actual engineering though. With a more refined and WAY better interior, the Camaro will be something that I'd love to have. The sightliness of the Camaro is also terrible, but that comes with that striking, if not extremely cartoony and goofy design. I don't treat the Camaro too seriously, and take it for what it is, therefore to me, it's a completely joyful and awesomely bada$$ to see.
