How to get a car when you have low income?

Basically I'm just trying to get a car and can't afford to pay for one entirely in cash, so I need a loan. Problem is I can't seem to get approved for one at all. My credit score is not the problem, I'm at 680, the problem is my income because I only make about 14k a year before taxes. I dont have anyone who can or is willing to cosign with me, nor can anyone lend me the money themselves. So I just really don't know what to do, am I just screwed until I can save up for a car, or are there possibly any other ways I could make this work? Any bit of advice is greatly appreciated, thank you
