I need a cheap car.

Does anyone know of someone selling a car that runs and drives for $700 or less? I know I'm looking for a miracle but I don't know where else to look or know what to do. I have looked in all the obvious places and have thought of all the obvious ideas. Transportation is my lifeline. I don't care about what kind of car or what it looks like I just need it to get me from A to B and back to A again for as long as I can do it.
