Following the end of World War II, Buick offered the widest selection of models in its history, and the sleek, rakish and luxurious Roadmaster continued to occupy the peak of the entire product range. Based upon the new General Motors C-body, the Roadmaster rode upon a long 126-inch wheelbase and was offered in a range of five body styles, including sedan, fastback sedanette, coupe, station wagon, and convertible models. These desirable cars received rave reviews from auto aficionados and increased showroom traffic at Buick dealerships.
A large part of the success must be attributed to Harley Earl, who successfully employed aircraft-inspired design themes in his vision for the ideal automobile. In addition, Buick added, for the first time, its trademark front fender portholes or Ventiports, another aircraft-inspired design theme that was developed by designer Ned Nickles, and reportedly tested on his personal car. Mechanically, the company introduced the Dynaflow fully automatic transmission as an option on the Series 70 Roadmaster model line in 1948. In fact, the Dynaflow proved so popular that Buick was quickly forced to double its schedule of proposed installations.
150bhp, 320 cu. in. inline eight-cylinder engine, Dynaflow automatic transmission, independent front suspension with coil springs, live rear axle with coil springs, and four-wheel hydraulic drum brakes. Wheelbase: 126"
