Seville Cadillac History 1984

Seville Cadillac Moels & History 1984

Restyled taillamps and new body-colored side moldings gave the bustleback front-drive Seville a slightly different look for 1984. Horizontal taillamps were modified to include a clear outer lens and red inner lens. This year’s grille had fine vertical accents and a bright script Cadillac nameplate in the lower left corner. The traditional Cadillac stand-up wreath-and-crest hood ornament stood on a tapered hood center molding. Seville had new low-gloss black door trim bezels, instrument panel bezels and air conditioning outlets. New tufted multi-button cloth or leather/vinyl trim were the upholstery choices for base models.

1984 Seville

New options included aluminum alloy wheels with center hubcaps and exposed chrome lug nuts. Sense-around Delco/Bose stereo was again available, and other sound systems were improved. Seville’s lengthy standard equipment included rear reading lights, accent moldings, manual seatback recliner, overhead assist handles, door pull straps, four-wheel power disc brakes, air conditioning, power windows, bumper guards and rub strips, and P205/75R15 steel-belted radial whitewall tires. The limited-edition Elegante could now be ordered in a single color instead of two-tone. That $3879 package included a leather-trimmed steering wheel, leather 40/40 dual comfort front seats (six-way power adjustment with recliners), console, Tampico carpeting, chrome side moldings, wire wheel covers, and deluxe floor mats.
