The first thing is lack of rubber under the car, they said it has none and that's pretty much impossible even if you clean it. It really doesn't fit any class but that doesn't mean it couldn't have been raced at some local track just for fun. The lack of any lettering or stickers. I do think someone was building the car and for some reason stopped. I absolutely love the car it is probably one of the coolest drag cars I've seen in awhile.
