“...the supreme instrument of luxurious motoring”

The year 1934 was an important one for Cadillac, marking the introduction of several new features. One notable innovation was the use of independent front suspension. This short and long arm front suspension system provided a much smoother ride compared to the previously used semi-elliptic leaf springs with a solid front axle configuration. Although independent front suspension was not a brand new concept in 1934, it had not been widely adopted during the early decades of the automobile industry when ride comfort was less of a priority. The research and design of the independent front suspension for Cadillac was overseen by engineer Maurice Olley, who had joined General Motors and Cadillac after the demise of his former employer Rolls-Royce of America in 1930. Olley brought valuable experience and expertise from his work at Rolls-Royce to help develop this improved suspension technology for Cadillac.

Cadillac models for 1934, including this Series 355D V8, showcased a sleeker overall design characterized by teardrop-shaped headlights, wing-like front and rear fenders, a sloping windshield, and a rear deck which concealed the chassis. The newly introduced streamlined “biplane” bumpers added a touch of elegance to the vehicles. However, due to high manufacturing costs and low durability, they were phased out after the 1934 production year. This fully restored example was originally purchased from Earle C. Anthony Inc. in California and represents one of the few remaining 355D Convertible Sedans left.
