Good luck to you, kid.
Stick by this, and you should be ok: Lose the car before you lose your credit if money becomes a problem. You can get another car (WRX) later. Getting your credit back is infinitely harder, and what you do now, early in your life, will stay with you. Remember, it's not just about having credit to be able to make purchases, but good credit will keep interest rates from devouring you as well.
