Cadillac Fleetwood Models & History 1973


Standard equipment on the Brougham included DeVille features (with different body underscores) plus:

  • Automatic Level Control
  • Dual-Comfort front seat
  • rear reading lights
  • a new front reading lamp
  • padded vinyl roof with rear chrome moldings
  • carpeted, rear compartment foot rests.

Four window, rounded corner roof styling, with extra wide center pillars, was seen again. Tires with pencil thin whitewall bands were used.


The long-wheelbase, high-dollar Fleetwoods were immense automobiles with low-cut, extra-large, rounded corner side window treatments and rather large “Coach windows” cut into the rear roof pillar. Fleetwoods had the annual Cadillac styling changes plus thin, horizontal body side moldings; front fender nameplates; full-length body underscores with rear extensions and Fleetwood style laurel wreath badge ornamentation. Equipment inclusions were carpeted foot rests; fixed ratio power steering; rear seat window defogger; Automatic Climate Control and righthand outside rear view mirrors operated by remote control. Bumper impact strips were standard on Seventy-Fives, optional on other Cadillacs.
