Yes, American cars were also popular like Ford's Cortina and Chevrolet's Impala were the most popular in Pakistan.
Further VW Beetle, Vauxhall Victor, Opel Kadet, Skoda, and Mercedez were also the famous brands in Pakistan. Citroen 2Cylinder Air Cooled Vintage was also there but not in large numbers.
