Many parts of this set have never been used. A couple of the pieces are still in plastic bags like they were from the original manufacturer. The only part missing on this is one of the tire treads on the small wheel, but you just don’t see hardly any formations where the small wheels are used all four at one time so it will most likely be a non-factor 99% of the time. You could also certainly strap a few wide rubber bands around the fourth wheel to give it some traction if you ever actually need to use all four at one time. All the pieces are in working order and great shape and the instruction book and the idea book all look like they are brand new as well. Box has been moved and stored thus the wear and tear on that. See photos for exact details of condition. Thanks for looking.
