Cars Rev Ups Rip stick Racer Collection: Inspired by hit Disney/Pixar animated films, Cars and Cars 2. It’s rip stick-like revving without a rip stick, meaning no pieces to lose. Kids simply rev up the vehicles by pulling the spoiler, then let go. The Disney/Pixar Cars vehicles will race and can also perform wheelies. Each sold separately, collect them all. Manufacturers recommended ages 4 and up.
