The all new Nissan Sentra gets an updated styling and an upgraded interior for 2004. The changes give the Sentra a more present-day appearance with a toothy grille reminiscent of the 2004 Maxima. New model trims, such as the1.8 S and 2.5 S, indicate which of two engines is under the hood. The Sentra remains practical and frugal, roomy and comfortable. In this site you will see the reviews made and the specs of the 2004 Nissan Sentra.
