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 we can have a smooth transaction. As shown in image 7, there is a chip. Please refrain from interacting if you are truly concerned about minor details. 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. Please also take a look at my profile. The following is for those who are interested. Here's the maintenance work performed: ★ Removal and cleaning of dust, hair, etc. from the wheels and motor unit of the power car. There may be some areas that couldn't be completely cleaned. ★ 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. ★ Replacement of rubber tires with new ones. Hard rubber tires won't be able to climb hills. That's the maintenance I've done. I haven't done anything more than that. I hope we have a good connection. m(_ _)m
