Personally I am not a fan of the camaro's exterior, but I do know that its performance is just crazy. Reviews are stellar for that machine. And of course the new interior will certainly be a step up, but none of those pluses can make up for my (subjective) view of the car. Also outright track performance is not what I'm into (which is why I've never looked into getting a C7, which I know is an amazing car), and I am somewhat unfairly biased against the mustang/camaro. Maybe that's because the wife likes the mustang so much and its apparently a rule that we can never agree on anything relating to cars.
The one American car I would buy though is the Ford Focus RS. Which is built in Germany
