In 2008 Hot Wheels released one of their coolest series, the Connect Cars. A special car for each of the 50 states in the United States. A highly collectible Hot Wheels car with the state name and a wild design painted on exterior. Why "Connect Car?" Each car comes with a hard plastic display case with the state name and outline pictured on the back wall. These plastic cases connect together like a building block. On the back side is a piece of the puzzle. When all 50 states are collected, they form an awesome picture of the American flag blowing in the breeze. This is a must have collection.
