Collectible Custom Made Ben Ten Go Cart

Our son won this Ben Ten Go Cart a few years back. A must for any kid that loves Ben Ten Cartoons. It's been stored in our garage all this time. It was custom made for this prize. The go carts has approximately 10 hours of driving time max on the engine. It has some scratches on the paint from storage nothing that a wax job can not take care of. It also comes with a custom made helmet that matches the go cart.
Approximate value of prize was $5,000. Need space in our garage to build office and our son has out grown. Only serious offers will be considered.
