A working car fund

I am raising money to purchase a used car. I work for an organization that helps traumatized and abused children and my time spent getting there and back every day takes upwards of 5 hrs. I would like to cut down on this time and finally have my own car. I work 2 jobs (this and another) and will still never have the extra money I need to do this. Having my own car will allow me to spend extra time on what I am passionate about - helping children when no one else will. There are not enough people out there willing to be the voice for those who cannot give their own. I'm not asking for much - I don't want a brand new car - just something that will allow me to devote those extra hours to these wonderful children who do not deserve the lot they've been given in life.
