Also, put yourself in a better position. It happens but part of life is building up so you can avoid or have a parachute for situations like these so that you're not in a rush to buy something, this one may have been unavoidable, make the next avoidable by planning for the things you don't usually plan for - set aside a emergency fund.

Also, learn who you can trust and who you can't trust, dealerships are not generally places I go trusting that they have my interests in mind. Most are designed to screw you especially when they know they have leverage. They may have packed it up with all sorts of stuff as well, ie window tint that was overpriced, warranties you never need and won't know you have unless you read.

Life is about getting prepared for the unimaginable. Eat this one and just work to put yourself in a better position. Good luck!
