Are you sure a copy is good enough? On the first page it says "original"....Also it says present the vehicle and docs. So you can present the docs(copy) 72 hours prior, and still show up with the bike later and drive through with it as long as they have the docs 72 hours prior?
13% aint bad, the price of the bike is good enough to still make it worth the road trip...
Maybe call that US Customs facility and ask? A fax has been fine for the five bikes i have brought over but that was always through Detroit.
