The winner, Tom Rumbel of Slippery Rock, was not present and has 30 days to claim his prize. He can choose between a red Chevy Impala, a white Buick Cascada or a blue GMC Terrain. The dealership held the drawing, which received 1,560 entries, to show gratitude toward its customers for their support over the past 25 years. “This was our way of thanking our customers for their commitment and time,” Troy Strezeski said. According to Strezeski, Troy-Alan Chevrolet-Buick-GMC has been a part of the Slippery Rock community since it started in 1993.
