At the Good News Garage, the motto is "donate a car, change a life," and since 1996, Hal and his team have changed the lives of more than 3,500 people. "It's a win-win situation. The donor gets a tax write-off from donating," he says. "And the recipient gets a car that they now can afford."

Watch Hal and his team at work.

Before donated cars go back on the road, a staff of mechanics assesses the vehicles and makes repairs. Then, they're sold at a reduced rate to people in need—80 percent of which are single moms.

Thanks to Hal's community garage, Dylan, a single mom who says she needs a car to go to job interviews and pick up her daughter from school, pays just $134 for a reconditioned sedan. "I'm so excited, I have to hug you," she says. "You guys are just amazing."
