There are, what, a dozen models of the Toyota on sale in the US?
Ever been to Tokyo? There are like sixty models of Toyotas driving around (maybe more). Really compelling body designs on some of these, too. Why do you think they limit the models in North America? I know plenty of them are assembled here in the US. Is that a factor? Tariffs? Anybody here knowledgable in the business side of Toyota?
OTOH, I didn't see any American cars in Tokyo.
