Should You Buy the 2006 Nissan Altima?

The 2006 Nissan Altima presents a compelling option for those seeking a spacious sedan, but it comes with a significant caveat: the 2.5L 4-cylinder engine carries a notorious pre-catalytic converter defect that can lead to catastrophic engine failure. While V6 models offer robust performance and better reliability, all variants require diligent pre-purchase inspection to avoid common suspension, steering, and rust issues, making it a 'proceed with caution' purchase rather than a 'buy with confidence' one.
