Up to now, Chrysler minivans mattered mostly to vacationers, out of town business folk and other purveyors of the rental car lots. Even with Stow ‘n Go, the innovative seat storage solution that debuted in the Grand Caravan and the Chrysler Town and Country a few years ago, retail sales declined and fleet sales went up. Dodge has plans to change that with its latest spate of minivan interior innovations. As with the Town and Country, the Grand Caravan offers swiveling mid-row chairs, a table, a five-way configurable center console and a power, one-touch third row seat. The only thing left to do is take the seats out and put in a dance floor.
