The Altima is one of Nissan’s best-selling vehicles. This year’s edition remains virtually unchanged, however, as plans are in the works for a 2005 redesign. The Altima is offered in the base 2.5, the 2.5 S, the 2.5 SL and the top-notch 3.5 SE. The standard engine is a 175 horsepower 2.5-liter gas-powered inline 4-cylinder, with the SE featuring a V6. While the Altima is not luxuriously equipped, it covers the basics, including power steering, windows and locks, front bucket seats, driver and passenger-side airbags, an anti-theft system, child safety rear door locks and fog lamps.
