I am looking to import the Polo because they have a diesel model that gets 70+ mpg. I talked to an importer who told me that the NHTSA has a list of cars you can import and that you would need $15 million to properly test the Polo and bring it in. This just doesn't sound right and they guy is a Smart Car dealer, so he might have been trying to steer me in that direction. Anyway, I really just want the great fuel economy and the ability to use biodiesel....anyone know how I can do this?
