Cadillac Models & History 1970

A relatively minor restyling marked the 1970 Cadillac Calais. A facelift included a 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 “vee” taillights were seen again, but no longer had smaller V-shaped bottom lenses pointing downward below the bumper. Wheel discs and winged crest fender tip emblems were new. A Calais signature script was placed above the rear end of the horizontal lower belt molding, just ahead of the chromed taillight dividers. Standard equipment included Turbo Hydramatic transmission; power steering; front disc brakes; power windows; center front arm rest; electric clock; two front cigarette lighters; twin front and rear ash trays; complete interior and exterior courtesy lamps; safety, warning, and convenience lights; outside remote control lefthand mirror; visor vanity mirror; and L78-15 bias fiberglass blackwall tires.
