Well, lets look at it here. *You have no real credit established. *You have very hard-to-prove income. *You have a cosigner with no car credit.

All of these raise flags for most banks, as you are considered a risky investment.

Luckily, you do have some money down, which can help, but you're still considered a risk.

The dealership is showing you a projection of what they think they can get you approved with. That does not mean, however, they have an approval in place. This is called subprime lending.

Provided that they can get you approved, this is going to be a very hard loan for you to deal with due to high interest and, as a result, a large amount of negative equity. This means you must pay it off in full, or have a considerable amount of money down to cover the negative next time you purchase a car.

I'm sorry OP, this is a hard place to be in. But, on another note, once you get this paid off, and on time with your payments, you'll be in a much better position to get another car.

Do you have a car right now? And are you in good standing with any banks at the moment?
