Support a Young Man's Journey to Work

This is my son from another mother. He is a strong young man who has been through more than most people would ever have to endure. Around 5 years ago, he received a life-saving kidney and pancreas transplant. As soon as he did, he got his GED and went to work. He walked, rode a bus, and did whatever he could to get to work. I gave him a car so he wouldn't have to walk to work. His immunity is low due to the transplant. Well, that car died. So I helped him buy another car, and then someone T-boned him and totaled the nice car. He went back to walking until I bought another car and was able to give him my older Jeep. And you guessed it, that Jeep is dying. I don't have any more funds to help, and all this young man wants to do is to be able to go to work. If you can help me help him, that would be awesome. I would either fix his car, or if we got enough, try to buy a decent car that might last a few years. I have always tried to help, but now, I need help to be able to do so. Thank you in advance if you can.
