This 67 Z-28 was an estate car that was on display in a plastic show case that is included. The car is listed as used because it was a display car. This car has no oxidation. I will be wrapping the cars in bubble wrap and then putting them back in the plastic show case and then a box for shipping. I do not ship overseas. Good luck bidding and God Bless our troops. All certificates I have are shown in pictures with the cars. If none are in pictures, I do not have any with that particular vehicle.
