The Series 355 featured a radiator screen, a single bar bumper and dual horns.

The new front end styling included a flat grille built into the radiator shell, head and side lights of streamlined bullet shape and the elimination of the fender tie bar and monogram bar.

Headlights featured three filament bulbs and four contour positions for degree and angle of illumination.

The vision of the driver was improved by 30 percent as a result of the elimination of the outside visor and the construction of a 12 degree sloping windshield and corner posts.

A three spoke steering wheel enabled an unobstructed view of the instrument cluster when in the straight ahead position.

The grille was made V-shaped and blended into the painted (chrome optional) radiator shell.

The most significant change in body detail was the introduction of "No Draft Individually Controlled Ventilation" (ICV) or pivoting vent windows in the front doors and the rear quarter or rear door windows.

Absence of a windshield operating mechanism on the closed car allowed room to conceal the wiper motor behind the headboard.

Changes in shock absorber valves extended the range of the ride control system.

Bumpers were a stylish but ineffective biplane design, mounted against telescoping springs.

Teardrop Guide Multibeam headlights were mounted on streamlined supports attached to the fenders.

The hood sills were high with the entire fender shape molded into the radiator shell.

Hoods extending nearly to the windshield carried shutter-type louvers in the side panel.

Added passenger space in the front compartment was achieved by moving the hand brake lever to the left of the driver, under the instrument panel.

On Fleetwood bodies the spare was concealed under the rear deck, unless optional fender mounts were specified.

Having been associated with funeral and ambulance equipment for many years, Cadillac embarked on an extra effort to consolidate this business in 1935 in its Fleetwood works.

Three Fleetwood bodied seven passenger livery sedans were offered on the Series 30 chassis.

Additionally a 160 in (4,060 mm) wheelbase commercial chassis was offered for hearse and ambulance adaptation.
