Nissan learned from its previous-generation (1995-99) Sentra that refined and nimble economy cars don't sell too well if they're boring. Economy cars face a lot of competition these days from bigger used cars, which are now off-lease and selling at attractive discounts. But many folks still prefer new, reasonably priced sedans with full warranties.

The term compact is relative, as all of these cars seem to grow over time. The Sentra pushes the boundaries of its industry classification. It is longer than other four-door compact sedans, and looks it.

The SE-R features an aggressive look all its own, with side-sill extensions, a rear spoiler, and chrome exhaust tips. New for 2003 is a bolder front fascia with large, integrated fog lights and a mesh grille, modeled after Nissan's legendary home-market Skyline sport coupe. The SE-R is particularly striking in Sunburst, a bright yellow that's also new for 2003.
