1983 Seville

Appearance changed little from 1982, except that this year’s grille had a bit less vertical look and carried a Cadillac script. The front end held clear park/signal lamp lenses. Seville could be ordered with a full cabriolet roof that simulated a convertible top, available in black, dark blue, white, or dark briar brown. Inside was Heather cloth upholstery with matching Rocaille cloth inserts, in choice of four colors; or optional leather in nine shades.

1983 Seville

A new premium sound system was available, using Dolby tape noise reduction. The 4.1-liter aluminum-block V-8 received a horsepower and torque boost in its second year, to improve a power-loss problem. Third-gear acceleration rate was also revised. The 5.7-liter diesel included an engine block heater to improve cold-weather startups. Seville Elegante again came in two-tone with French curve side styling using chrome bodyside moldings, plus “Elegante” script on the side panels and accent striping. Four two-tone combinations were offered. Sierra Grain tucked leather seating areas were color-coordinated to match the body color, and to complement the leather-trimmed steering wheel. The front console was leather-topped. Wire wheel covers were standard.
