RE: What is the expected price for the Challenger?
I'm not flaming you for what you want, I don't blame you for wanting a nice performance car. I'd want one too at 16. I and others are trying to get you to see reality. I've lost friends to car accidents because of younger drivers. I worked with kids in their teens who were killed because they were hot dogging and misjudged curves in the road at 70 mph. One guy in particular on a suicide crotch rocket showboating hit a tree head on. The fire crew had to peel parts of his body out of the bark of the tree. They are all statistics. The hardest thing for a young kid to do is listen to advice when they have their sites set on something they want bad.
Don't confuse advice for condemnation. Only you will know if you have the will power to refrain from a kid in an STI taunting you and calling you out.
