most: the headlights that light up, the opportunity to honk the car with the central button on the remote (A use can be a bit noisy?) and glignotant that light up on the remote control when the car turns !
Indoor car in my opinion (if only for security reasons) that fishing (it mounts easily on the left blanket stalls ...).
Note: in the car (the front wheels), there is a knob. This one corrects the trajectory if the car is not running right when pressing the button "forward". If the car seems to be unwieldy (turns more on one side than the other, am not a straight path ...), check this setting, it is possible that your child has pushed the button on one side or on the other!
a good quality / price ratio (30 euros purchased in December 2011).
