You or a broker must pick the car up in Canada and bring it across the border - "import". The "seller" cannot bring it across for you - "export" !!

Under the existing auto pact, you can import any Canadian-made car. The U.S. border guards might shoot you for taking away U.S. jobs but screw 'em !!

In Canada we have a "Registrar of Imported Vehicles" website that explains what we need to do to import a vehicle I would think the U.S. has such a thing also.
