Oh, and here is some fun from the EPA website:
"Importers need to verify whether the Canadian vehicle they are importing is identical to a U.S. certified version. For model year 2002 and beyond, the majority of Canadian vehicles are acceptable for importation into the U.S. without modification. There may be specific models that are Canadian-only packages that are not eligible for importation into the U.S. Any questions about Canadian-only models will be treated on a case-by-case basis. (Refer to options 2 and 3 below)."
