Help a Trans Woman Get Her Car Back

I am a trans woman and I have an unexpected emergency car fix that needs to get done. I took my car to a drive thru oil change place and it lead to me sitting there for hours as the technicians messed around with the car trying to fix a mistake I warned them not to touch in the first place. When they finally gave up trying to fix it, suddenly the car wouldn't start. Even with a a new battery installed.

They agreed to take the car to the mechanic around the way and cover costs IF they were related to anything their technicians did. Of course, they decided that they had nothing to do with breaking my car and now I'm stuck with a massive bill if I want to get my car back.

i live in a rural area. Personal transportation is essential. I can not live with a car. The car has a lot of miles on it and if this does well enough I'll buy a new used one but at the very least I need to be able to get my old one back.

anything, even a share, is greatly appreciated it.
