Twin rectangular lamps on each side of the grille; it features five horizontal zones
and thirty-six vertical ones; the Cadillac script graces the top RH side of the
grille shroud;   DeVille models feature a free-standing crest, while the
Fleetwoods have the well-known, stand-up wreath and crest

There was not a standard front clip for the entire model range; this is the one for
the Fleetwood and DeVille models;  the Eldorado and Seville had their own

The Fleetwood sedan has a new, limousine-style rear window for added privacy,
as well as opera lamps mounted on the "B" pillars; wheel covers too are new

   
Interior trim (right) is the optional leather one in saddle; there were ten shades of leather in all;
standard trim was a knit material in slate gray, dark blue, dark green, saddle, light beige and dark claret

The Brougham came also in the d'Elegance configuration [ what a horrible misuse of part of the French concours d'élégance ]; 
the latter featured an even smaller rear window than the new, regular Brougham back-light, a wrap-around roof quarter panel,
the D'Elegance script on the sail panel; interior trim was either the knit pillow style in slate dray, dark blue, saddle, dark claret
and light  beige (right)  or genuine leather seating areas in light beige, slate gray, saddle, dark blue and dark claret (below, left)

   
Three distinctive interiors were offered on the Coupe de Ville, shown here with the optional Cabriolet roof treatment
(a throw back to the thirties!); it featured a chrome cross-over molding, French seam and opera lamps; interiors were trimmed
in six shades of Durand knit cloth with velours inserts; four shades of Venetian velours were available in the DeVille
d'Elegance, as were also ten shades of leather  (dark carmine is shown at right)

The d'Elegance version of the DeVille models came with pillow-style seating
of soft, Venetian velours in slate gray, light beige, dark claret and dark blue (above);
there was also a DeVille d'Elegance script on the glove-box door as well as
on the roof sail panel; opera lamps were optional on the DeVille sedan

Eldorado's egg-crate grille this year comprised seven horizontal zones (the lowest one
being partly hidden) and eighteen vertical ones; a wreath and crest graced the front hood

   
The Eldorado featured  4-wheel independent suspension as well as 4-wheel disc brakes with automatic adjustment;
the classic coupe (above, left is shown in Colonial yellow); interior trim was six shades of Heather knit material
or 10 shades of leather (but only for the seating areas)

      
The Biarritz version had cast aluminum wheels and a brushed stainless steel roof a la 1957-58 Eldorado Brougham, with a wide
cross-over chrome molding; opera lamps and the Biarritz script graced the cabriolet style sail panels; interiors featured tufted pillow style seating
in seven shades of leather (seating areas only) or in slate gray knit material; the Elk grain cabriolet roof was available in in seven colors

The regular limousine could accommodate eight people; the formal version had a sliding glass partition
and seating for seven; black leather trim was used in the front compartment of the formal limousine
Right: heather cloth interior, available also in slate gray and black 

   
This set of original factory photos illustrates very well the new "bustle-back" Cadillac Seville for 1980

       
At center is the standard Heather cloth interior, shown here in dark blue; saddle leather seating areas were available at extra cost (right)

Top: the regular, plain Seville; below it, the more luxurious Seville Elegante, now a correct
use of the French word (but badly  pronounced as "eleGANTAY" instead of "eleGAUNT")

   
The Elegante script, with wreath and crest, decorates the roof sail panel; chrome-plated wire wheel covers (shown)
were available at no extra cost; three 2-tone paint combinations were offered: black and gray, two shades of gray
and two shades of  brown (shown, right); leather seating areas were standard as was a leather trimmed steering wheel
and a leather-topped center console; two shades of leather were available: light beige (shown) or slate gray

       
The Seville's distinctive grille this year comprised three horizontal zones and twenty-eight vertical ones;
again, a wreath and crest graced the front hood; "bustle-back" styling aped a James Young design from the UK
