The Kitchener, Ontario Toyota sales manager says he has never done an 'export' sale--been there a few years, he said.
ebay has a couple of sellers selling Canadian-market models of vehicles that are DOT-certified for US, i.e. Sienna/Sequoia/Tundra. I'm still researching--next call is to TMS to see if they would know anything about adding the 5-dr for '08--but at this point, I'm thinking the xA is going to be much easier route...
