Make your Darda Racing sets more fun with additional cars! These fully-assembled models come ready to use with a unique friction-powered motor that runs without batteries or electricity. Simply push down and push the car back and forth a few times to wind the motor, and when bumped from behind by another car, they take off from the starting line!
