Released in 1992-1993, the Pro Circuit cars where based on real racers in Indy, Drag, and Stock Racing. Each car came with a trading card.
Due to Hot Wheels being a toy for children, Mattel would censor out any sponsors related to drugs. The results are interesting and are pointed out below.
NOTE: Images of Sealed Cars with the extra Trading Card are stand-ins at the moment. When an image of just the Trading Card is available, they should be replaced.
