Eldorado Cadillac Moels & History 1983

Like other Caddies, Eldorado saw no major changes in its body this year, though the automatic transmission and cruise control were recalibrated to boost performance. Standard engine was the HT-4100 4.1-liter V-8 with its complex (yet reliable) fuel injection system; optional, a 5.7-liter diesel.

Prices began at $19,334 (suggested retail), which included plenty of standard equipment. The grille was similar to DeVille/Fleetwood, with Cadillac script at the driver’s side in the center row. Front fender tips held no lights, so the quad rectangular headlamps and horizontal-style parking/signal lamps had a recessed look. Cornering lamps were in horizontal housings back on the front fenders. Heather cloth upholstery with Rocaille cloth inserts came in four colors; or buyers could choose from ten leather choices. Options included a digital instrument cluster with readouts for fuel level, speed and fuel range (English or metric).

1983 Eldorado

Eldorado’s convertible had been gone for some time, but the optional full cabriolet roof simulated a convertible top, with canvas-look fabric, roof bows and waited seams. It came in black, dark blue, dark briar brown, and white. Eldorados had a new optional premium sound system, as well as available aluminum wheels. Two special editions were offered again: the Touring Coupe and Biarritz. Touring Coupes had (no surprise) a touring suspension, large-diameter stabilizer bars, larger P225/70R15 steel-belted radial tires, and special cloisonne hood medallion. Only two body colors were available: Sonora Saddle Firemist (light brown) and Sable Black. Reclining saddle leather-faced front bucket seats offered lumbar and lateral support, and included a console. Eldorado’s Biarritz “dream machine” included a brushed stainless steel roof cap, wire wheel covers, opera lamps, and “Biarritz” script on the sail panels. Tufted pillow-style seats came in Sierra Grain leather in six colors; so did the steering wheel.
