Currently at Square One, Mississauga, General Motors has a setup in the food court area. Among the sniny new cars up for a trst drive, you can enter a draw to win one of those plus a trip to the 2010 Olympics. After entering, you are given a choice between either a GM recyclable bag (approx. $1-2), a slide puzzle ($1), or the Transformers Universe Chevy Aveo Swerve figure (approx. $20 on the Chevrolet online store) for free.
