* Trim Level: The Impala was the top-of-the-line model, while the Bel Air sat in the middle. Below the Bel Air was the Biscayne, the entry-level model. This meant the Impala boasted more luxurious features and styling cues.
* Styling: While both shared the iconic 1959 Chevrolet styling (the finned tailfins are a key feature of both!), the Impala featured more elaborate trim, including unique badging, fancier interior appointments, and sometimes more chrome and ornamentation. Think of it as the difference between a nicely dressed person and someone dressed extravagantly.
* Interior: Impala interiors were generally more luxurious, with better upholstery (often including leather options), more comfortable seating, and more advanced features. Bel Airs offered a more functional, less lavish interior.
* Options: Impalas were often more likely to have optional features already included or easily available as upgrades (such as power options, air conditioning, etc.) These could sometimes be added to Bel Airs but were less common and often cost extra.
* Price: The Impala was significantly more expensive than the Bel Air, reflecting its higher trim level and added features.
In short: They were siblings sharing the same family DNA but with the Impala being the "dressed-up" version, offering more luxury and style at a premium price. Both, however, are highly sought-after classic cars today.
