1989 Cadillac Sedan deVille

For unclear reasons, one, but only one, of the supermarkets in my area often has interesting eighties cars parked outside. Today, despite the snow on the ground, there was a 1989 Cadillac Sedan deVille on “display” with classic car tags—good enough reason for this blog entry.

“… the definitive full-size luxury car”

Cadillac’s Sedan deVille was substantially revised for 1989, marking the first time that it had been “up-sized” for almost two decades. Overall length increased by nearly nine inches, while the wheelbase increased by three inches. The styling of this C-body was more in the traditional Cadillac vein than the 1985-1988 cars, with vertical blades in the rear that somewhat resembled the fins of previous decades. Changes extended to the interior, with more comfortable seats and more room in the rear compartment. New options included a heated windshield defogger ($250) and a Delco-Bose stereo with compact disc player ($872).

Standard power for the front-wheel-drive Sedan deVille continued to be the transverse-mounted HT 155 bhp 4.5 liter/273 ci V8 with throttle-body fuel injection paired with a Turbo Hydramatic 4T60 four-speed automatic transmission. 0-60 mph took about 10 seconds in the 3,470-pound car. Mileage was 17 city/25 highway by the standards of the day (15/23 by today’s standards)—with an 18-gallon gas tank, a deVille owner could expect a range of about 310 to 340 miles with a 10% fuel reserve.

Standard exterior and mechanical equipment on the $25,760 Sedan deVille (about $52,900 in today’s dollars) included tungsten-halogen headlamps, power rack-and-pinion steering, power brakes, four-wheel independent suspension, and P205/70R15 tires on 15-inch wheels. Inside, a Sedan deVille was well equipped: air conditioning, six-way power driver’s seat, tilt and telescope steering wheel, cruise control, power side mirrors, power windows (including an express-down driver’s side window), power door locks, and an AM/FM stereo with cassette player were all standard.

Exterior and mechanical options for the 1989 Sedan deVille included anti-lock brakes ($749), aluminum alloy wheels ($480), Astroroof ($1,355), and rear window defogger ($270). Inside a theft deterrent system ($225), leather seating areas ($560), and digital information cluster ($250) were available.

Reviews of the revised Sedan deVille were generally good, and it sold well. Cadillac shipped 122,693, making it by far Cadillac’s most successful model for the year—the rear-wheel-drive D-body Brougham was a distant second place with 28,926.

According to Hagerty’s valuation tools, all the money for a 1989 Sedan deVille in #1/Concours condition is $5,400, with a far more typical #3/Good car going for a mere $2,800 (only the top-of-the-line Allantés do decently among late eighties Cadillacs). This generation of deVilles does maintain a presence in the Hemming’s Motor News classifieds and on eBay Motors. As I write this in December 2017, there’s a black 1991 with 89,000 miles for sale, asking $10,300.

Make mine Medium Garnet Red Metallic, please. Another C-body I have covered in this blog is the 1985 Oldsmobile Ninety-Eight Regency sedan.
