Seville Cadillac Models & History 1985

For its final season in this form, the front-drive Seville sedan changed little. Neither did its companion Eldorado, which used the same chassis layout. Standard engine, as before, was the fuel-injected 250 cu. in. (4.1 liter) V-8, with four-speed overdrive automatic transmission. Buyers could also choose a diesel V-8, but not many did. Seville’s base price was $23,729. New to the option list: aluminum alloy wheels with a radial fin design and gray accents. Both spoked and non-spoke versions were available. Seville’s Elegante had a new “Inner Shield” windshield with a two-section plastic layer intended to prevent cuts from splintered glass in an accident. Elegante’s interior featured standard leather seats, color-coordinated with the car body. Late in the model year, a Commemorative Edition package was announced.
