should have looked at their license plates if it wasn’t Canadian plates, it simply ment they shipped it by a boat for a temporary use in Canada, my friends do that all the time in England and else where in europe it actually cost less to do that than go for vacation and rent a car for a month.
Though i doubt that person owned the holden commodore SS in canada, unless the car was from Australia and 15 years old, because the North American market only got the new Pontiac GTO recently from 2004 i think, which is basically the newer Holden Platform and the Middle east has the Lumina SS.
If the person did have Canadian plates, he could have purchased the car elsewhere Australia or State, and transfered the ownership to Canada, because the Holden is exactly the same as the GTO which was released to the North Americas in 2004.
