The 2005 Nissan Sentra belongs to the 5th generation of the Sentra lineup, a staple of Nissan's compact car segment. It offers a lineup of three trims: the 1.8, 1.8 S, and performance-oriented SE-R. Engine options include a base 1.8-liter 4-cylinder engine delivering 126 hp and a more potent 2.5-liter 4-cylinder engine churning out 165 hp on SE-R models. Transmission options are versatile, with the choices of a 4-speed automatic, a 5-speed or 6-speed manual. The Sentra comes equipped with standard safety features of the mid-2000s, including front-seat side airbags and child safety rear door locks. In terms of tech, it offers comfort features such as air conditioning, power windows and mirrors, and a CD audio system. The SE-R trim adds a sporty character with larger wheels, sport-tuned suspension, and bolstered seats.
