1958, GM ended production of its two-door sport wagons, as the slow-selling Nomad and Safari had both served as the most expensive cars sold by Chevrolet and Pontiac. While the two-door sport wagons had been retired (as consumer tastes had largely shifted away from two-door wagons), both nameplates saw further use, with both divisions again using them for redesigned station wagons. Following its adoption by the B-body chassis during 1957, Pontiac returned the Safari for 1958, using the nameplate as a secondary series designation. 1958-1965 For 1958, Pontiac offered a Safari for the Chieftain and Star Chief ranges. The Transcontinental wagon returned, taking the Star Chief Custom Safari nameplate of the previous two-door wagon (the Bonneville remained a hardtop/convertible). For 1959, Pontiac revised its model range, introducing the Catalina Safari and Bonneville Safari (the Star Chief remained, becoming sedan-only). The Bonneville was offered with two rows of seating; the Catalina was offered with either two or three rows of seats. Following a slight downsizing for 1961, the Safari returned as part of the Catalina and Bonneville series, with the 9-passenger option remaining exclusive to Catalina Safaris. For 1965, full-size Pontiacs underwent a redesign, with the Safari again returning as a part of the Catalina and Bonneville series. For the exterior, a vinyl roof was introduced as an option. 1966-1970 For 1966, the Safari nameplate was dropped by Pontiac, as its B-body station wagons (Catalina and Bonneville) deleted the secondary series designation. For 1967, the Safari nameplate returned for the newly introduced Pontiac Executive full-size station wagon (replacing the Star Chief) and the top level Bonneville Safari, with the term "Safari" used to identify exterior woodgrain trim for the first time; all three wagons were now offered with third-row seating. 1971-1976 For 1971, Pontiac revised its station wagon branding, making the Safari a stand-alone model series based on the Catalina. The Bonneville station wagon was dropped in favor of the Grand Safari, which itself was based on the Grand Ville series. In 1973 the Grand Safari also adopted exterior woodgrain trim. Officially designated as a B-body vehicle, the Safari (and its Buick/Oldsmobile counterparts) shared the 127-inch wheelbase of the C-body "senior" sedan chassis. For 1974, the Safari again became a secondary series designation, becoming part of the Catalina range.; the model line adopted the rectangular headlights introduced on full-size Pontiacs for 1975.
