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 operational 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 need additional images so that we can have a smooth transaction. Honestly, please refrain from contacting me if you are overly sensitive. I have other items for sale. If you wish to purchase multiple items, please use the "request bulk purchase" function to consult with me. I will almost always accept requests, except for manual input of the desired price. I would also appreciate it if you could take a look at my profile. Please see below if you are interested. Here are the work details. ★ Removal and cleaning of dust, hair, etc. around the wheels and motor unit of the power car. There may be some parts that cannot be completely removed. ★ Independent maintenance of the motor. Restoring the original condition of the motor. 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 products. The above are the maintenance details. I haven't done anything more than this. I hope we can have a good relationship. (bow)
