No, I think they can but they do it best in their own plants in Japan, but the profit margins are so slim it makes no sense to import them outside of the home market since the cars are made very specifically for the country. Toyota partners up with other companies when it makes good business sense. Profit margins for the previous Yaris were tough having to import from Japan and France, so its not surprising that they could make the Mazda2 into their entry level vehicle that was already being built in Mexico.
good and cheap though? I dont think they can do that... they build good small cars. they can build cheap small cars. But they cant built good and small cheap cars on their own... Etios is the living proof.
