Calais Cadillac Models & History 1976

For its final outing, Calais displayed the same front-end look as the more expensive DeVille, with a Cadillac “V” and crest at the hood front. Interiors could be Morgan Plaid in four possible color combinations, or expanded vinyl in antique light buckskin or black. Standard features included

  • an AM/FM radio with automatic power antenna
  • automatic climate control
  • digital clock
  • tinted glass
  • lamp monitors
  • power door locks

Sedans had small coach windows on the rear pillar; coupes much larger, squarish rear quarter windows. Rear fenders held script nameplates. Electronic fuel injection had become optional on the 500 cu. in. V-8 in March 1975, but the carbureted version continued as standard.
