The Pontiac Star Chief is an automobile model which was manufactured by Pontiac between 1954 and 1966. It was Pontiac's top trim package on the Pontiac Chieftain, with later generations built on longer wheelbases, and serving as the foundation platform for the Pontiac Bonneville. The car was easily identified by its chrome star trim along its sides, a feature all Star Chiefs were equipped.
Fourth generation (1959-1960)
In 1959, when the Bonneville gained a full range of body styles, the Star Chief was limited to sedans and hardtops, while the Bonneville and the new Catalina models received the lion's share of Pontiac's attention in the marketplace. In 1959, the Star Chief made 17.97% of Pontiac sales. This was also the first year of the "wide-track" Pontiacs.
In 1960, the new Ventura was introduced, and the Star Chief was thereafter limited to four door sedans and hardtops. This was a novel, but unsuccessful approach. The Star Chief was equipped and powered in a manner similar to the lower-priced, slightly smaller Catalina series. The Ventura was more lavishly equipped in the manner of the high-line Bonneville, but was available with only two doors and rode the Catalina's slightly shorter wheelbase. This gave sedan buyers of modest means a larger choice than Catalina for only slightly more money, and gave upscale coupe buyers a lighter, sprightlier alternative to the big Bonneville. The Ventura lasted only through 1961, and was replaced by the even sportier new Grand Prix. The Star Chief continued to be available only with four doors through the end of production. Compared to the Catalina, the Star Chief was equipped only very slightly more lavishly; the major additional interior feature was the electric clock.
