The 2011 Lancer has remarkably well-designed seating. In front, the front seats are a little larger and better bolstered than most small-car perches, and they give a nice, upright driving position and decent long-distance comfort; the sport seats in the GTS are even better. In back, legroom is right, but there's just enough headroom for adults (just two, ideally).
The five-door Sportback body style is offered now in ES and GTS trims and brings a little more cargo space and versatility—especially if you fold the backseats forward. Otherwise, backseat space is identical between the two.
On any of these models, noise and ride comfort could be deal-breakers. DE and ES models come with a slightly softer suspension and more forgiving tires that comfort-oriented buyers will probably prefer. But especially in GTS form, the Lancer rides quite hard, however, with plenty of road noise to match the engine noise. The roar of the engine is mostly an issue in CVT models, where the engine gets raucous and buzzy on acceleration. Also bringing a downmarket feel to the Lancer is the collection of decidedly basic materials used in the cabin; there's lots of hard, hollow-sounding plastic.
