Well guys...I own both cars..I posted pics of them together. The GT500 is a rocket,like a thrill ride everytime I get in it..I can tell you this,It won't dissapoint you in the performance dept.. Styling...I love the front of the car..Back it's not as good.. The Challenger..I think the styling is tops,a great take on a classic style. smooth looks with out gimmicks. Performance: So so. doesn't feel like 425hp..more like 350hp. no great rush of power. don't get me wrong,I like this car,but more power is needed to compete with the GT500...I think the car will be faster and feel faster with the 6 spd.
