Childs car using feet to move it (Woodley RG6)

Old style car gifted to me secondhand and I only used indoors during my possession. Still a lot of wear in it. The fuel cap was pushed through hole, so taped it up to stop anything else being pushed in. Apart from that it's faded, that's it. Child moves it along with feet, it steers and one only door opens, the other is fixed.
