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 worked 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 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 combined purchase" feature. I will almost always accept requests, except for manual price input. Please also take a look at my profile. Below, please take a look 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 areas that cannot be completely removed. ★ Independent maintenance of the motor. Restoring the motor to its original condition. Since I have not replaced it with an aftermarket motor, you may be able to request repairs from the manufacturer. They will not accept modified products. ★ Replacement of rubber tires with new ones. Hard rubber tires will not be able to climb hills. ★ Exterior cleaning using various cleaners. The above is the maintenance content. I have not done anything more than this. May you have a good relationship (m(_ _)m)
