Does anyone have a cheap car I could buy? Doesn’t have to be running mainly a place to sleep

Hey everyone, unfortunately today is my first day trying to figure out what to do with nowhere to stay. I am looking for a super cheap car, all I have on me is a little over $300. I know it's a shot in the dark, but maybe someone has a car that they don't want anymore. I'm also willing to work so if that's how you roll. I'm very willing to work for it along with the money I have. Currently alone with nothing but the clothes on my back and my phone and wallet. Any advice is appreciated!

To be clear I'm not asking for donations or help! Just wondering what options for cars are there for someone in my financial situation
