Diecast Shelby Mustang SP-1 Series are remote controlled and the doors open too. The diecast Shelby is controlled via the included watch remote control that fits on any size wrist. Drive forwards, backwards, left, and right. Real sound effects let you hear the horn, idling car engine, and screeching tires when the car is stopped. Press a button on the watch and the car turns on with the simulated engine noise. Yes, it has an anti-theft alarm too! This is the ultimate diecast Shelby SP1. Don't play with regular diecast cars when you can have a remote controlled diecast Mustang. Requires 2 AA batteries and measures about 6 inches long.
