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 would like additional images, so that we can have a smooth transaction. Seriously, please refrain from interacting if you are overly sensitive. I have other items for sale as well. If you wish to purchase multiple items, please use the "request combined purchase" function. I will almost always accept requests, except for manual entry of the desired price. I would also appreciate it if you could take a look at my profile. For those who are interested, please see below. Here are the maintenance details. ★ Removal and cleaning of dust, hair, etc. from the wheels and motor unit of the powered car. There may be some parts that cannot be completely removed. ★ Independent maintenance of the motor. Restoring the motor to its original condition. I have not replaced it with an aftermarket motor, so you may be able to request repairs from the manufacturer. They will not accept modified products. ★ Replacement of rubber tires with new ones. The vehicle cannot climb hills with hardened rubber tires. ★ Cleaning of the exterior using various cleaners. The above are the maintenance details. I have not done anything more than this. I hope we have a good relationship m(_ _)m
