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 if you'd like additional images, so that we can have a smooth transaction. Really, please refrain from interacting if you are overly sensitive. 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 your 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 power car. There may be some parts that cannot be completely removed. ★ Independent maintenance of the motor. Restored the motor to its original condition. I haven't replaced it with an aftermarket motor, so it should be possible to request repairs from the manufacturer. They will not accept modified items. ★ Replacement of rubber tires with new ones. Hard rubber tires will not be able to climb hills. ★ Cleaning of the exterior using various cleaners. The above is the maintenance content. I have not done anything more than this. I hope we have a good connection m(_ _)m
