Should I just Get a car to live out of?

I (24F) live with my boyfriend (21M) and his family. When we started dating, we were both working at a factory making a decent wage. We both quit for mental health reasons and have both been applying for different jobs....I got one a few months ago, worked for a little while, and then they fired me the day before New Year's Eve because I changed my availability in order to stop my manager from scheduling me for doubles (which kept landing me in the hospital). My boyfriend hasn't had any luck with applying for jobs at all. I've also been knitting and crocheting clothes and other items to sell online to make some extra cash with no luck.... The other week, my boyfriend's dad started asking for rent...even though he knows neither of us currently have any income. He wants $200 from each of us, which would be reasonable if we had jobs or even a running vehicle. Yesterday I received an interview request for a job I have been hoping for. Today I was getting ready, only to be told we don't have any running vehicles to get to my interview. I am beside myself.. How am I supposed to do this? Every time my boyfriend works outside the farm, his dad (who is the person that wanted the farm in the first place) complains that he's too "lazy". His dad also makes me extremely uncomfortable because he has intentionally exposed himself to me numerous times, while also stating he quit teaching because he was "not allowed to touch the students anymore." He has made it nearly impossible to find and maintain work anywhere, for either of us. My boyfriend has been working the farm under the premise that his dad will pay him...well he hasn't paid anything yet and I don't think he's going to. I don't know what to do. I'm so frustrated and I just want us to both get jobs, a running vehicle, and our own place. I don't even care if we live out of a car for a while. It would be better than this tbh...
