So ask your cousin where he "scored" that big scholarship!
FAFSA is based on your/your parents' tax filing. FAFSA didn't "screw you a little". So either you had a sibling that's no longer in school or your parent's tax returns showed a higher income or maybe (someone with this info off the top of your head please chime in) the income protection amount might have changed this year. Who knows. But no, they didn't screw you. You /your parents bought a car you can't afford. You screwed yourself.
If you think they are going to give you more FA because you bought and have to pay for an expensive car, (and maintain 2 of them)I have a bridge to sell you. That really made me truly LOL.
Don't know where you attend school, but those grades/test scores are not competitive for any scholarships. But you know that.
Sell one of the cars and pay for college. Its worth more in the long run than the car.
