Transporting to and fron Canada?
Mike, in my case they wanted a copy of the title showing the title is clear & who the new purchaser is, and an agreed purchase price faxed to U.S. customs. That way they could easily clear it when it arrived there. The new owner then presents the bill of sale & new title at customs. Mine was being trailered back by me since it was sold 'as is' and not plated.
The purchaser needs to take care of this. Once its purchased, its really their problem to see that they can get it home.
