^ Its an official document, And yes the mileage is totaly genuine on it, How ever the mileage on the auction sheet can be higher then that on the export certificate. But not less then what is on the export certificate.
For instance, I sold my car in japan, and its export certificate was made to be sold, But it wasnt sold, Then later some auction house bought it so mean while it was being driven here and there, But once a car is auctioned, it is transported to the shipyard or port so it cannot be driven at all.
