The Series 60 (new last year) added a new Convertible Sedan body style. Throughout the line there were a few body changes including:

• Eggcrate grill and hood louvers
• Higher fenders with lengthwise crease along the top
• Set of three horizontal bars each side of grill
• Bumpers carrying the Cadillac emblem
• Swinging rear quarter windows
• All steel body construction

Series 60 shared many features with the LaSalle, but used the 5.678 Liter V-8 engine. A Series 60 Commercial Chassis with 4074mm wheelbase was offered.

The new Series 37-65 was offered in only one body style--a five passenger Touring Sedan built by Fisher on the 3327mm wheelbase used on Series 70 cars.

This car was longer and heavier than the Series 60 at a price below that of the Fleetwood bodies cars.

The Series 37-70 and 37-75 bodies were the same as the corresponding 1936 models except for:

• Drip molding running from the bottom of the front pillar up and over the doors and rear quarter window
• New fenders and bumpers
• Headlights rigidly attached (adjusted by moving reflector)
• Wheel discs incorporated a hub cap
• Built-in trunk used on most bodies

• A diecast eggcrate grill was used, but the hood louver treatment differed from that used on Fisher bodied cars.
• Chrome diecast strips were used at the rear of the hood side panels.
• A seven passenger Fisher bodied Special Touring Sedan, with or without division, was offered on the 3505mm wheelbase.
• These two body styles had the eggcrate hood louvers typical of all Fisher bodied Cadillacs for 1937.
• The Business Car line included eight passenger versions of these Special Sedans plus eight passenger versions of four Fleetwood body styles.
• The eighth passenger was seated with two others on the auxiliary seats.
• A Commercial Chassis on a 3962mm wheelbase was offered.
