Cadillac Calais History 1973
CALAIS |
---|
New energy absorbing bumpers were seen on GM cars this year and brought Cadillac styling refinements with them. Grilles were widened and had an intricate egg crate design. Larger, vertical rectangles housed the parking lamps between wide spaced headlamps, which had square bezels, but round lenses. Bumpers ran fully across the front of the cars and wrapped around each end. Vertical guards were spaced much wider apart, at a point outboard of the grille. The rear end had a bumper with a wider, flatter upper section housing an angled license plate recess. Border outline moldings, vertically “veed,” paralleled the fender edge shape at the rear body sides. Single, rectangular rear side marker lamps, horizontally mounted, were placed over and under the rear tip of the thin belt line trim. Cadillac scripts were seen on the front fender sides, below the belt molding, behind the wheel opening. Cloth upholstery was standard and equipment features were comparable to 1972.
