I don't usually promote a charity but I came across this site and it struck me as a terrific idea. 800 Charity Cars. Check them out HERE. They help struggling families with transportation in the form of giving them their own cars. It looks like they accept cars or you can donate money (scroll to the bottom of the home page for $$ donation link.)
If you don't have a car to donate now, maybe you can bookmark it. Later, when your neighbor is trying to figure out how to unload his hooptie you can come to his rescue and give him the link.
I just know from personal experience how difficult it is to raise a family without personal transportation. Doctor appmts, emergencies, getting to the stores with the best sales... sometimes just getting out of the house for a short drive to keep a mother from leaping off Insanity Ledge.
(for those who may not be familar with a "hooptie", just think of a car costing $500 or less.)
