No problem with our Mexican plated car to Canada. I was amazed actually. Our only problem was that the car wash in Canada said it was too dirty to be cleaned there and had to take some mud off it before they would wash it with their car wash brushes. Well, I had sprayed it with oil and drove it around La Manzailla to make it look like one would not be interested in stealing it. Ha. Worked and we were never stopped.
