In a similar manner - if you aren't driving a "north american" car you're not even allowed to park in any of the close lots at the local GM plant. you basically park further away then everybody else as your punishment. When mixed with the large price discount for buying from GM it is basically a fool's game to buy anything other than a GM here. If you're an employee/partner/supplier/ or know an employee/partner/supplier.
For the rest of us who don't get discounts.... the world is our overpriced oyster.
