AMC Compact buyer's guide

Overview

AMC's compacts after the Rambler American (1970–83) — Hornet, Gremlin, Concord and Spirit — were Kenosha's answer to the 1970s: economical hatchbacks, sedans and wagons on the Hornet's unibody platform, carrying AMC's sixes and (early on) its small V8s, and including two genuine performance footnotes — the Hornet SC/360 (1971) and the Gremlin X — plus the car that defined AMC's eccentric image, the Gremlin itself (1970–78), America's first modern subcompact hatchback. These are affordable, characterful classics whose values live on originality and condition; the SC/360 is the documented rarity, the Gremlin the pop-culture icon, and the Concord the comfortable last word.

Generations and year breaks

1970–1977 — Hornet and Gremlin

• The Hornet (1970) replaced the American: sedan, hatchback coupe (from 1973, the "Touring Wagon" hatch) and the Sportabout wagon, with the 199/232/258 sixes and the 304/360 V8s.
• The Gremlin (1970): the Hornet with its tail cut off — a Kammback subcompact launched on April Fool's Day, sold with a sense of humour and (as the Gremlin X) stripes and buckets.
• Hornet SC/360 (1971): the SC/Rambler formula in the Hornet — the 360 two/four-barrel, one year only, registry-documented territory.

1978–1983 — Concord, Spirit and the Eagle's dawn

• The Concord (1978) civilised the Hornet into AMC's mainstream compact-luxury car; the Spirit (1979) replaced the Gremlin with a proper hatchback and coupe.
• The Eagle (1980, the all-wheel-drive line on this platform) is a family of its own story; the rear-drive compacts ended with the Concord and Spirit in 1983.

Engines and options that matter

• 199/232/258 sixes — the 258 is the usable engine and the line's backbone; the four-cylinder cars (the Audi/VW 2.0 of the late Gremlins, and the Pontiac Iron Duke in early-80s cars) are economy footnotes.
• 304 and 360 V8s — the Hornet could be a genuine compact muscle car; the SC/360's four-barrel 360 is the collectible specification, verified by its codes and the registry.
• Gremlin X and Levi's interiors (the denim-trimmed cars of 1973–78) are the option packages the market recognises — the Levi's trim's condition is the car's premium.
• The hatchback Hornet and the Sportabout wagon are the practical classics of the range.

What to check before buying

• Rust: the Hornet platform's unibody rot — front subframe sections, floor pans, rear quarters, the hatch and wagon tailgate surrounds. As with all AMC cars, structure decides the purchase.
• SC/360 verification: the VIN (the SC/360 was built on the Hornet two-door sedan body) and the engine codes, plus the hobby registry — the package's rarity makes paperwork the value.
• Engine identity: AMC sixes and V8s are coded on the block/rocker tags; bought-in fours (VW/Audi 2.0, Iron Duke) are correct for their years and identified by their own stampings.
• Gremlin specifics: the rear glass and its seal, the cut-off tail's seams, and the fuel tank area (behind the axle) deserve a look on the early cars.
• Parts: the AMC specialist network covers the sixes and V8s well; compact-specific trim, Gremlin glass and Levi's interior material are the hunts.
