The Altima is Nissan's most versatile car. It can perform a number of chameleon-like changes, allowing it to shine as low-priced four-cylinder family sedan, stun as a mid-level near-luxury car or awe as a flat-out performer that leaves butterflies in the stomach. The Altima is roomy, handsome and frugal, three characteristics that are quite appealing these days. Toss in Nissan's bullet-proof reliability record, and the Altima becomes a viable alternative choice to the ever-popular and omnipresent Honda Accord and Toyota Camry.
