Save our only vehicle

My husband went through a very rough financial issue, and got so far behind on car payments. He is still having issues making the payments as he is the only one working while I'm home with 1 of our children. He was told that they are going to repo the car if he cant come up with the money. He still also need inspection and parts for his car so he can pass inspection. We can not afford a new car let alone a used car.
