The Packard Twelfth Series One-Twenty is an automobile produced by the Packard Motor Car Company of Detroit, Michigan, from 1935 to 1937 and from 1939 through the 1941 model years. The One-Twenty model designation was derived from the wheelbase, and it was replaced by the Packard 200. The One-Twenty signified the first time that Packard had entered into the highly competitive mid-priced eight-cylinder car market. Packard enthusiasts view the production of the One-Twenty and the Six/One-Ten models as the start of Packard's losing its hold on the market as the premier American luxury automotive brand. It was a marketing strategy shared with GM's LaSalle, the Chrysler Airstream, and the Lincoln-Zephyr. It was introduced after Rolls-Royce brought to market the Rolls-Royce Twenty, which was manufactured between 1922 and 1929 (succeeded by the Rolls-Royce 20/25 which was built until 1936). The introduction of the One-Twenty (and later the Six/One-Ten models) was a necessary move to keep Packard in business during the final years of the Great Depression, expanding on an earlier approach with the Packard Light Eight. Branding the One-Twenty a Packard afforded buyers the cachet of owning a Packard. Other reasons the company decided to forgo the development of a companion brand name to sell the less expensive models may have been linked to its single production line capability at its Grand Boulevard manufacturing plant or to the expense of launching a new brand of automobile. It also ushered in a novel advertising approach, commissioning an advertising "jingle" called "When Heaven Was at the Corner of Sycamore and Main". The Safe-T-Flex suspension This car introduced the independent front suspension to the Packard line. Its so-called "Safe-T-Flex" suspension was an unequal upper and lower A-arm type with the largest possible lower A-arm composed of two different arms bolted together at a ninety-degree angle. The support arm was a heavy steel forging reaching a few degrees forward of lateral from the front wheel support to as close to the centerline of the car as is practicable. An integral pad socketed the helical spring, whose upper end reached a high frame cross-beam. A tubular, hence lighter, steel torque arm was bolted to the support arm somewhat inboard of the wheel to permit a sufficient steering arc. It reached the frame nearly at the dashboard with a spherical rubber bearing. The upper A-arm was conventionally welded and oriented parallel to the lower one. Between it
