Jeff's point is well made. Also provides documentation for proof of origin when crossing an international border....the customs officers are inconsistent in asking for ownerships, but if you have nothing to prove that you were in possession of the vehicle upon entry to your neighbor's country, be prepared to have a prolonged stay with the border folks.

As I see it, it just makes life easier for everyone and helps to expedite a sale.

If a car never leaves your hands and you do not plan to compete in Canada or Mexico.....it probably doesn't matter.
