Although I think its Shape is more refined, but if they brought this to US it will never sell here.
They like the Undaa style Mini-Vans here, like Chrysler and Dodge Caravan. The Japanese tried to enter the US mini-van market with Toyota Townace, as I see them occasionaly, but those are very rare and because of the Boxy shape, never got to be a hit.
A Stavic (more closer to the egg shape ) would sell alot more in US, than this Japanse style mini-van.
