Just beside this article is another very beautiful article about how the EV9 was internationally voted by a renowned board of automotive experts who are no doubt highly educated, wealthy and affluent; the best vehicle in entire world. That's planet earth for you numbskulls. Let me repeat: the best vehicle in the world is the Kia EV9.
