Thank you for viewing. This is a completed Mini 4WD model. I bought it new from a hobby shop about 15 years ago. I built it, but I never had a track, and I forgot to get motors and batteries, so I've kept it stored away. Therefore, although I built it, I've never run it, so I don't know if it works. I've kept it stored in the original box. This was made by an amateur, so please refrain from purchasing if you are concerned. Thank you.
