Since people don’t buy minivans for performance or prestige, cargo and convenience are critical elements to get right. The 2006 Kia Sedona lags behind the competition on this front, its maximum 141.5 cubic feet of cargo space unable to match the heavy-hitters in the segment from Chrysler, Dodge, Honda, and Toyota. If you’re using the Sedona for an airport run, there are 32.2 cubes to work with behind the third-row seat.
