We agree with Huey Lewis: It is hip to be square, at least when it comes to a car like the Nissan Cube. The polarizing squares-meet-circles design theme gets a lot of attention, but the Cube’s attractiveness is more than skin deep, with features like a sliding and reclining second-row seat, an overabundance of head room and a headliner design that mimics the concentric circles created by a pebble dropped into a pond. Zen is the original cool, right? All told, the Nissan Cube is an exceptionally practical and modestly priced car, but it's not for everyone. And everyone knows the key to being cool is not caring what everyone thinks.
