Mazda has won critical and public acclaim for its Nagare series of dream cars, and the 2010 Mazda 3 that debuted at the 2008 L.A. Auto Show is the first production car where some of that lineage is clearly evident. The pronounced grille opening in front and flowing fenders all remind us of those concept cars, but the result is still a practical, comfortable and attractive compact sedan. Want to drive a dream car to work? Here you go.
