This vehicle has been maintained by an amateur so that you can enjoy it for a long time. Of course, the operation has been confirmed. My operation check means confirming that it runs properly. It's not just "it moved when I put in batteries, so it's good!" Please feel free to comment if you have any concerns or need additional images so that we can have a smooth transaction. Honestly, please do not engage if you are overly concerned about details. I have other items for sale. If you wish to purchase multiple items, please use the "request bulk purchase" function to consult with me. I will almost always accept requests, except for manual input of the desired price. I would also appreciate it if you could take a look at my profile. Please read on if you are interested. Here are the maintenance details: ★ Removal and cleaning of dust, hair, etc. around the wheels and motor unit of the powered car. Some parts may not be completely removed. ★ Gear replacement and cleaning. The vehicle will not run properly if the gears are broken. For example, it won't climb hills. There are repair marks from the replacement work. ★ Independent maintenance of the motor. Restoring the motor to its original condition. I haven't replaced it with an aftermarket motor, so you might be able to request repairs from the manufacturer. They won't accept modified items. ★ Replacement of rubber tires with new ones. Hard rubber tires will not allow the vehicle to climb hills. ★ Exterior cleaning using various cleaners. The above is the maintenance content. I haven't done anything more than that. I hope we have a good connection. m(_ _)m
