Help Sarah get a car

Hey everyone! As some of you may know, i was in a car accident on sep 27. Prior to, my car was continuously dying on me and i actually had an appointment at the mechanics on monday. However, after this accident and all the other problems with my car that has nearly 200k miles on it, it’s time for me to look for another car. I don’t have great credit, nor do i have a co signer, so i’m trying to raise money for a down payment so i can get back on the road and to and from work. any and all help will be so greatly appreciated. I hate asking for help, but when it’s needed, it’s needed. Thank you in advance.
