Used Nissan Altima Sedans

Nearly everything but the engines is either all or substantially new, beginning with the Altima's "class-above" looks, inside and out, and extending to a raft of new features, some class-exclusive. The CVT automatic transmission, thoroughly revamped for pleaseability and efficiency, accounts for much of its class-leading fuel economy.

Changes for 2012 are limited to a new Value Package that includes Bluetooth hands-free phone connectivity, auto on/off headlights, a leather-wrapped steering wheel with audio controls, and HomeLink. Bluetooth is now standard on the 3.5 SR and available on the 2.5 S.

For 2011, the Altima gains a new Special Edition trim (Altima 2.5 S) adding an aerodynamic rear spoiler, front fog lights, auto on/off headlamps, 16-inch alloy wheels and a leather-wrapped three-spoke steering wheel with audio controls.

For 2010, the Altima receives a revised hood, front fascia and wheel designs, as well as new fabrics and interior trim. All models now feature Vehicle Dynamic Control (VDC) as standard equipment and last year's 3.5 SE is rebadged as the 3.5 SR.

The base 2.5 model receives more standard features including new 16-inch wheel covers, a CVT automatic transmission, power side mirrors, a trip computer and outside temperature gauge. The 3.5 SE trim receives Vehicle Dynamic Control (VDC), HID headlamps, fog lamps and a rear spoiler.

The key Altima enhancement for 2008 is anti-lock brakes becoming standard across the entire line. Also new to the mix are splash guards, a diversity antenna and the availability of XM Satellite Radio as a factory-installed option.

Slightly smaller in this fourth generation, Nissan's midsize sedan can have an Xtronic continuously variable transmission (CVT) for the first time. Striving for the best-performing front-wheel-drive sedan in the world, Nissan claims to have addressed perceived weaknesses of the 2002 through 2006 models, including interior quality, noise levels and steering effort.
