Economy cars are purchased for a number of reasons, yet add a quiet ride to that list and you're typically setting yourself up for disappointment. Not so with the 2007 Nissan Versa, a model that is designed to keep out a surprising amount of noise. There's some non-intrusive wind whistling at highway speeds, minimal road noise, and squealing tires that accompany every corner attacked with the slightest bit of spirit, yet none of it is terribly bothersome, and all is well within the expected bounds of an economy car. Even the four-cylinder engine is quiet except for when it's wrung out, at which point it remains relatively refined.
