The 2003 Nissan Sentra is part of the model's sixth generation. This compact sedan came in four trims: XE, GXE, SE-R, and SE-R Spec V. The base 1.8L four-cylinder engine generates 126 horsepower and is paired with a 5-speed manual or 4-speed automatic transmission, but the SE-R trims offer a sportier 2.5L four-cylinder with 165-175 horsepower. Standard features include power mirrors and a CD player, while higher trims add amenities like power windows and locks, alloy wheels, a rear spoiler, and a leather-wrapped steering wheel. The Sentra earned high safety ratings for its time, including four stars from NHTSA for frontal impact.
