There’s that old adage that says if you’re at the bottom, the only way to go is up. One could argue that’s an apt description of the rocket-like ascension of the dynamic Korean duo of Hyundai and Kia in the past five years.

Not only does the new 2006 model improve upon its predecessor in nearly every way imaginable, those improvements amount to a competitive subcompact that can go toe-to-toe with the likes of the Scion xA and Chevy Aveo. We should know, we reviewed it, too.
