RE: What is the expected price for the Challenger?
I'm more worried about the other drivers on the road than you. It's the family approaching you that would be the victims should you test your prowess and lose control. The more people on here try and forewarn and advise you the more cocky you get. I can only imagine how cocky you'd get when someone challenges you in the car.
Long and short of it is... at 16 you lack the confidence and experience to be driving a car like this.
