Where can I get approved for car financing on disability?

I make $803 per month and have poor credit. My FICO score from Experian was 589 last I checked. I now have a late payment on my credit card and I used and exceeded the credit limit of $200. How this is possible I don’t know. I also have a late payment on the Laptop I bought on credit from Aaron’s because it was stolen. I need a car and I know there are places that help people with government income. I don’t care about location or interest rate I just need options.
