Packard introduced the eight-cylinder One-Twenty in 1935, its first entry into the medium-price field. So successful, Packard was prompted to offer a six-cylinder model dubbed simply “Six” in 1937, calling it the One-Ten starting in 1940. The two so-called “Junior” models quickly became best-sellers for Packard as they accounted for over 92-percent of production by 1940. The company continued to divide the cars between Junior and Senior models, but the emphasis was now on the Junior models with sales coming increasingly from the lower end of the price spectrum. The public was the beneficiary as the One-Ten and One-Twenty models offered legendary Packard quality for the price of a Buick, Olds, Mercury, Hudson, or DeSoto.

Despite being Packard’s lowest-price eight-cylinder car line, the One-Twenty was by no means a base model. Equipped with Packard’s 120-hp, 282-cid straight eight and three-speed transmission, performance was excellent. The Convertible Coupe, model 1399 was quite an attractive car, and at $1,275 with a leather interior, quite a value, too.
