Mazda2 is also an older model that hasn't had much advertising. Its sales have been declining for a few years and it's due to be replaced for 2015 along with the Yaris (the 2 companies are collaborating ... sharing a platform and development costs).

The auto reviewers almost always pick the mazda2 as their choice - because it's the most fun to drive in the small car class. Yet it hasn't sold in big numbers. Goes to show how journalists and buyers in the real world have very different priorities.
