Getting GT or challenger in college?

So I’m going into college this August, and I’m thinking about getting a new car. I have a jeep that I could get 15k on roughly. Since I was little my dream car was either a challenger or a mustang. I’m not really a jeep guy anyways, so I was thinking about selling it, and getting a used challenger or GT for 10-15k. I don’t need very much storage, and I don’t plan on having very many people in my car. Only problem is I’ve only been driving off and on for about a year and I’m definitely no expert yet. Should I hold off for a few years and rack up some more driving experience before I make the jump? Should I just spend less and get a challenger? What do you guys think?
