The big difference with these cars is that they are more practical than Camaros and Mustangs. You can reliably use the back seats for transportation, especially in the 300C and Charger. Comparing a 300C and a Camaro is ridiculous. The only car in this group competing against the Camaro is the Challenger, and even at that it's still a much bigger car. I gotta agree that an SRT8 isn't going to win a drag race with a ZL1 or GT500, but the people buying these cars already know that.
If I was going to buy one, I'd buy about a 2 year old model when they drop down what they are really worth. I wouldn't spend that kind of cash on a new Dodge or Chrysler. That Jeep, on the other hand, is one of the hottest SUVs on the road, even up there with the Cayenne turbo in performance. It may be worth a look in comparison to say an X5 M. Just sayin!
