This vehicle has been maintained by an amateur so that it can be enjoyed 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!" To ensure a smooth transaction for both parties, feel free to comment if you have any questions or would like additional images. Seriously, please refrain from contacting me if you are overly concerned with details. I have other items for sale. If you wish to purchase multiple items, please use the "request to bundle" function and discuss it with me. I will almost always accept requests, except for the manual input of the desired price. Please also take a look at my profile. The following information is for those who are interested. 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 areas that cannot be completely cleaned. ★ Independent maintenance of the motor. The motor's original condition has been restored. Since the motor has not been replaced with an aftermarket motor, it may be possible to request repairs from the manufacturer. They will not accept modified items. ★ Replacement of rubber tires with new ones. Hard, brittle rubber tires will not allow the vehicle to climb hills. ★ Exterior cleaning using various cleaners. The above are the maintenance details. I have not done anything more than this. May you have a good connection with this item. m(_ _)m
