AS people-movers go, the Mitsubishi Nimbus once belonged at the smaller end of the scale but has grown over the years to rival the Honda Odyssey and Toyota Spacia. Closer to Odyssey in concept, but more of a decent jump than a quantum leap over the Honda in refinement and road manners. The driving position remains car-like and the floor shift beats the Honda's column shift, hands-down. Yet it still offers a walk-through cabin and great versatility that allows an impressive range of seating/sleeping/cargo configurations.
