As we all anxiously await how Nissan will screw up the next Sentra, the company unveiled a number of small vehicles in Japan that may make their way to the states as a step below the Sentra. Top among the contenders is the Cube. With its box shape it closely resembles the Scion xB. But my money is on the small Tiida hatchback. It looks like a shrunken version of the Quest Minivan and more closely follows the design trends of the company's U.S. models. Worst among the group is the Tiida sedan which looks almost identical to a Toyota Echo. And no one likes them.
