The Cadillac Series 70 (models 70 and 75) is a full-size V8-powered series of cars that were produced by Cadillac from the 1930s to the 1980s. It replaced the 1935 355E as the company's mainstream car just as the much less expensive Series 60 was introduced. The Series 72 and 67 were similar to the Series 75 but the 72 and 67 were produced on a slightly shorter and longer wheelbase respectively. The Series 72 was only produced in 1940 and the Series 67 was only produced in 1941 and 1942. For much of the postwar era, it was the top-of-the-line Cadillac, and was Cadillac's factory-built limousine offering.
Production of the short wheelbase Series 70 ceased in 1938, but reappeared briefly as the relatively expensive Series 70 Eldorado Brougham 4-door hardtop from 1957 to 1958, while the long wheelbase Series 75 made a final appearance in the 1987 model year.
A relatively minor restyling marked 1970 Cadillacs. A face lift included a new grille with 13 vertical blades set against a delicately cross-hatched rectangular opening. The bright metal headlamp surrounds were bordered with body color to give a more refined look. Narrow vertical taillights were seen again, but no longer had smaller V-chaped bottom lenses pointing downward below the bumper. Wheel discs and winged crest fender tip emblems were new. Special equipment found on the big Cadillac sedan and limousine included automatic level control; rear window defogger; four rear ashtrays and manual right-hand outside rearview mirror. Separate climate control systems were provided for front and rear compartments. Fleetwood wreath crests appeared at the extreme edge of the rear fenders, above the belt molding, on both the sedan and the limousine. As usual, the doors on the limousine cut into the roof and a fixed driver's partition with adjustable glass compartment divider was inside. The front compartment was trimmed in genuine leather, the rear in one of five combinations. Three of these were the more standard Divan cloth trim, while Decardo cloth or Dumbarton cloth with leather were the richest selections available.
