<human>: Can you condense the text into a few key points?

I know nothing about credit, but here we go. A few years ago I was going through some huge problems with my money and myself, got kicked out of my parents house, got my car repo'd was dipping and dodging all kinds of debt. 3 years later I've paid all debt off and I'm 100% better and I feel I'm ready to start making payments on a new again. But seriously doubt anyone would give me a 2nd shot. Can't have anyone co sign because my pops did on the car I got repo'd. Since then paid back the $7,000 they put up to get the car back.
<bot>: I have bad credit, Tired of car issues, just want a new one! Any hope? If so, ELI5.
