The all-new 2007 Nissan Altima is a midsize car with the performance and feel of a luxury sedan, at least in the model with the V6 engine and options. The basic models come with a strong four-cylinder engine. The Altima is roomier, safer, more comfortable and more economical than before, and has stylish new looks. It's a thorough improvement from top to bottom, inside and out. Based on the track record of Nissan engineering, it would be hard to go wrong with a new Altima.
