* Bel Air: This was arguably the *most* popular Chevrolet model throughout the 1950s. It offered a good balance of style, performance, and affordability, moving upmarket from its predecessors. The 1957 Bel Air, in particular, is iconic for its design.
* 150 (and its various names): This was Chevrolet's entry-level model, and it went by different names throughout the decade (like "One-Fifty"). It wasn't as flashy as the Bel Air but was significantly more affordable, making it a popular choice.
* 210: This was the mid-range model, sitting between the 150 and the Bel Air in terms of features and price.
While the above three are the major players, it's worth noting that Chevy also offered other variations and packages within these models that contributed to their overall popularity. The specific popularity of each model fluctuated year to year based on styling changes and economic conditions.
