Downsized the year before, Eldorado entered 1980 with few significant
changes beyond a bolder crosshatch grille pattern, dominated by
vertical bars. Its upper horizontal bar, with Cadillac script,
peaked forward and upward. Quad rectangular headlamps sat above
amber-lensed parking/signal lamps, with wide horizontal cornering
lamps on the fenders. An Eldorado script was behind the front
wheel openings, just above the bodyside molding. Wide rocker
panel moldings stretched all the way front to rear. Atop the hood
was a Cadillac wreath and crest. New two-tone paint schemes were
offered. Multi-slot style wheel covers were standard. So was
Heather knit-cloth pillow-type front upholstery, offered in six
colors for the Dual Comfort 50/45 front seats (for two people).
Customers could also select from 10 leather possibilities.
The instrument panel featured simulated
teak woodgrain. Eldorado enjoyed an improved EPA fuel mileage
rating as a result of the 6.0-liter V-8 with electronic fuel
injection. A new MPG Sentinel was available with the DFI engine,
which also offered new on-board computer diagnostics. New
Electronic Climate Control offered digital accuracy. An optional
Cabriolet roof of textured Elk Grain vinyl came in 15 colors,
including matching Firemist shades. The optional theft-deterrent
system now disabled the starter motor.
Eldorado Biarritz rode cast aluminum
wheels and carried a number of unique styling accents, including
an exclusive brushed stainless steel front roof section. The wide
chrome molding crossing over that roof continued all the way to
the front fenders. Biarritz script and opera lamps enhanced the
rear roof pillars, and the model also featured accent stripes.
Inside, the tufted pillow-style interior came in seven leather
choices; or slate gray Heather knit fabric. The steering wheel
was leather-trimmed. Biarritz carried a price tag of $18,003,
compared to $15,509 for a base Eldorado.
