This vehicle has been maintained by an amateur to ensure 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, please feel free to comment if you have any questions or would like additional images. Seriously, 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 combined purchase" function. I will almost always accept requests, except for manually entering your desired price. Please also take a look at my profile. The following is for those who are interested. Here's the maintenance performed: ★ Removal and cleaning of dust, hair, etc. from the wheels and motor unit of the powered car. Some parts may not be completely cleaned. ★ Gear replacement and cleaning. If the gears are broken, the vehicle will not run properly. This can especially affect its ability to climb hills. There are repair marks from the replacement work. ★ Independent motor maintenance. 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. ★ Exterior cleaning using various cleaners. The above is the maintenance performed. I haven't done anything more than that. I hope we have a good connection. m(_ _)m
