In Japan, this car is called Boon. It has a double entendre of English word "boon" and the engine sound (the Japanese onomatopoeia of engine sound is pronounced like "boon"). Toyota also sells this car, rebadgeing with Toyota badges and renaming it Passo....Liked, but isn't this a Sirion? What's up with...."Boon"? Is it a "Boon" to drive? Is that why it's called a Boon?
