I have a 1999 Wilco recreation vehicle for sale. Truck has never been removed from boxed in my opinion after inspecting item. That is just opinion...I myself have not removed it. Truck seems to be clean of stains or "yellowing" with all inserts and battery card in box. There is no sign of leakage from batteries on the box. Box is in good condition with minor shelf wear. Item would be great piece for any collector of gas, auto, or toys. Thank You and enjoy.
