Its the US customs that want the paperwork. They want to do lien and theft searches on the car before it leaves the country and they want it 72 hours before (sometimes it includes weekends, sometimes not, all the rules change all the time). They will then stamp the title that it has cleared US customs. You can fax it but call and confirm they have received it. I've gotten to the border before and they claim they never got it. What it was is that when they received it they couldn't read it 100% clearly so they just throw it in the garbage and don't inform anyone.
