Oy. I went through that fifteen years ago. My problem was that my previous car was older than any of the charitable organizations were willing to take, even though none of their advertisements would have you believe there are any such restrictions. And then I couldn't find (guess what?) -- the title, and I had to pay to get another from the DMV. Finally, the kidney foundation was willing to take it and boy was that a relief. I think I still had to pay 50 bucks or something for the towing, not sure, but that may have been routine for all of them. Don't remember now, and don't want to. It was a drawn out nightmare.
