JoAnne Colucci was at Chevrolet of Homewood on Christmas Eve to pick up a new car she won in the second annual Homewood Chevy Cares contest, but she didn't want to talk only about the car. She wanted to talk about how the contest had expanded the reach for her family's story. The contest, which begins with nominations on Nov. 1, seeks to find a person or family whose life would be changed most by receiving a new car. Nominations are followed by online voting to determine five finalists. One of the finalists receives a free car.
