you are almost talking apples to oranges when it comes to a Mustang GT or a Charger R/T. they have different functions. The Mustang is a true sports car and the Charger is more of a family car.
I like the looks of the Charger on the outside, but on the inside it looks very cheap in my opinion.
I wouldn't swap my Mustang for a Charger even if you paid me 10 large on top of the trade.
