<prompt> Human: I also currently live at home, cover my own expenses, except my parents wont accept rent, and make about 900 per paycheck. I have a paid off used car worth about 4500 and am considering upgrading to a muscle car in the 20k range which my family is supportive of. But before I make any decision like that I wanted to know what the smart choice to do with this kind of money would be.  <response>: Dumping all your cash into a muscle car while you still live with your parents is a losing move. Upgrade your life, not your vehicle.
