48: Sunbird GT
The GM J Body platform saw a lot of changes over three decades, and Pontiac was a part of this. At one point every GM brand had a car that was based on the J Body, even Cadillac as scary as that sounds. The original Sunbird GT was not a bad car by any stretch of the word, and a lot of the styling was better received than the Cavalier. But Pontiac had a problem with quality in the long run that made the Sunbird fall out of favor. Toyota was coming on strong with the Corolla as was Honda with the Civic.

As time went on, the GM J Body cars were increasingly simplistic and lacking in features. The Sunbird GT was a great entry point for buyers who needed something affordable. But as time went on the cars were less innovative and this leads to a decline in quality. Nevertheless, the Sunbird GT was at one point one of the most popular cars in the GM lineup. The Pontiac badge and the signature styling made it stand out from the crowd.
