Help Izzy Stay Mobile & Employed!

Hey y'all,
So I hate begging for shit but I'm really in a bind here. My car needs about $3000 worth of repairs, which is considerably more than I payed for it, so I'm gonna need a new car.
Having a car is the main thing that enables me to be stable and independent as a disabled person;  it allows me to have a job, to easily get to medical appointments, and to pursue my career as a musician. Without one I'm pretty well fucked.
I'm fairly confident that I can find a decent car for about $3000. I've got a little bit saved up from work, but since my current job doesn't pay hourly, it's not much, and I have a number of other important expenses I need to cover.
I wouldn't be asking for help if I didn't really need it. Whatever you can give is appreciated. 
Thank you so much.
