Nissan Sentra gets updated styling and an upgraded interior for 2004. The changes give the Sentra a more contemporary appearance with a toothy grille reminiscent of the 2004 Maxima. New model designations (such as 1.8 S and 2.5 S) indicate which of two engines is under the hood. The basic product and its mission have not changed, however. The Sentra remains practical and frugal, roomy and comfortable. Sentra offers a good value, starting at just $12,200 (MSRP) with a well-equipped 1.8 S retailing for $14,200. The SE-R models are solid sport compacts, fun to drive, with a responsive suspension and a strong, 165-horsepower 2.5-liter engine. For 2004, Sentra models get redesigned front and rear fascia and a newly styled hood. Also receiving changes for 2004 is the Sentra SE-R. New features include a new brake package for SE-R Spec V with Brembo front discs, a new interior charcoal fabric and two new exterior colors � Volcanic Orange and Sapphire Blue. There are several interior upgrades as well, including a trip computer (standard on 2.5 S, SE-R and SE-R Spec V) and an enhanced Rockford Fosgate sound system.
