Both the controller and the vehicle have some rust in the battery box, but they powered on and moved. However, the rubber tires are not original, so there is some wobbling when running. I confirmed the operation of running, forward/reverse switching, horn, and lights. Sometimes the response is slow, but it responds when the batteries are replaced or the unit is turned on and off. I have not checked it by running it on a layout. Also, some of the terminals in the controller's battery box are a little loose, but I don't think there's a problem. There is also no lid.
