Cadillac Seville Buyer's Guide

The Cadillac Seville represents Cadillac's most significant strategic pivot since the postwar era: a deliberate, sophisticated answer to the import luxury threat from Mercedes-Benz and BMW. Smaller, lighter, and more refined than any Cadillac before it, the Seville proved that American luxury could adapt to the 1970s energy crisis without sacrificing prestige. Today it is an affordable, elegant classic that rewards the discerning buyer who looks past badge snobbery.

What to Check Before Buying

✓

Test EFI system through cold start, warm idle, and hot restart (1975–1979) —

✓

Inspect Nova-platform floor pans and rocker panels for rust —

✓

Test all vacuum-operated accessories (windows, locks, climate) —

✓

On HT4100 cars: look for white exhaust, overheating history, and verify head bolt condition —

✓

Verify A/C function or assess R-12 to R-134a retrofit cost —

✓

Inspect leather interior condition — correct color/grain replacement is expensive —

✓

Check for diesel engine (identify by badging and exhaust color) — verify complete rebuild if present —

✓

Confirm trunk and interior dry — no water intrusion from roof or quarter windows —

Common Issues

The Bendix EFI on first-generation cars needs attention on most survivors — hot-start issues and lean surge are common. HT4100 head gaskets and head bolt thread pull-out are the defining problem of 1982–1984 cars — many have been poorly repaired. Diesel V8s require complete rebuilds if not recently done. Nova-based structure rusts in the usual floor and rocker locations.

What to Look For

The ideal Seville is a first-generation 1977–1979 car in a classic color combination — Cotillion White/Antique Saddle or Firethorn Red/Antique Parchment — with a sorted EFI system and dry, rust-free structure. These cars are still regularly found as estate vehicles with modest mileage and careful ownership. Avoid any car described as 'just needs the engine sorted' on HT4100 generations.

Price Guide

First-gen 1976–1979: $6,000–$12,000 driver; $14,000–$20,000 detailed. 1980–1981 bustle-back: $5,000–$14,000. 1982–1985 HT4100: $3,000–$8,000 (engine risk makes higher prices unjustifiable without specialist documentation). EFI rebuild budget: $800–$1,500.

Did You Know?

The Seville was the only American car with standard electronic fuel injection when it debuted in 1975. Its Nova platform underpinnings were the worst-kept secret in Detroit, yet the execution was so convincing that Road & Track compared it favorably to the Mercedes-Benz 280S. The bustle-back 1980 design was inspired by Hooper-bodied Rolls-Royces of the 1940s and 1950s — a direct reference to British coachbuilding tradition.
