Help For a Car

My name is Jamario Carr, I'm a 22 year old male who is currently living on my own. I just recently came out of a 3 year long homeless situation about a year ago. I was able to save enough money to buy my first car which cost me 800 dollars. I tried since I was 19 to buy a car and I wasn't having any luck. The reason being I had no credit or no savings. Since I got my car I've spent more money on it than what I paid for it and now its giving me problems that are scary and to expensive for me to afford. My job requires me to use my car all day long so I'm in desperate need of a car. I'm asking 5,000 but anything would help. even if that means another 800 car to get me from A to C for the next 6 months. thank you!
