http://oldcarandtruckpictur.../buick1950-1959.htmlyea, wikiIn 1952 Buick's mid-priced line resembled the Series 40 with three VentiPorts per fender and Sweepspear rocker panel trim. Super script appeared on the rear fenders aided identification. The Super was built with the larger C-body, however. The full flowing fenderline dipped deeper on this body and rear fenders had a rear crest line absent on the B-body Specials. A new deck lid gave a more squared off appearance. Like other Buick series it was a near copy year for 1952. Chromed rear fender fins gave distinction to 1952 Supers. Interiors were cloth except on convertibles and Estate wagons which were trimmed with leather. The Super used a different instrument panel than the Special. It was distinguished by a large center speedometer housing flanked by smaller gauge housings. Series identification was found within the steering wheel center. The Sedanet and the regular wheelbase sedan were cancelled. Sales fell to 135,332.
In 1953 Buick's middle priced line shared the Roadmaster's new V8 and, for this year the Roadmaster shared the Super and Special's 121.5 in (3,086 mm) wheelbase. The Super earned a horizontal trim bar on its rear fenders which distinguished it from the Series 70 Roadmasters. Otherwise its side trim bar on its rear fenders was identical although the Super was had only three VentiPorts on each front fender. Series identification was found on the deck emblem. Full wheelcovers were now standard. The vee in the bombsight ornament signified the V8 power under the hood. Interiors in most models were nylon and silky broadcloth. The convertible had power windows, seat and top as standard equipment. Dynaflow was now standard equipment. Air conditioning was a new option. A total of 190,514 Supers were sold.
