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 price input. I would also appreciate it if you could take a look at my profile. Please see below 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. There may be some parts that cannot be completely removed. ★ Independent maintenance of the motor. Restoring the motor to its original condition. Since I haven't replaced it with an aftermarket motor, you may be able to request repairs from the manufacturer. They won't accept modified items. ★ Cleaning of the exterior using various cleaners. The above are the maintenance details. I haven't done anything more than this. I hope we have a good relationship m(_ _)m
