3 - Tracksters - They're sorta like Webkinz, only for cars. You buy the Hot Wheels sized die cast cars, but that's only half the story. You get a code with each car to enter online to get your car activated. Once you have your car, you can race it, hop it up (with codes from packs of cards sold separately), give it a new paint job. Not your daddy's Hot Wheels. It's sorta like a toy and video game all wrapped into one!
