Among the 34 Ligier entries in the MotorJury library, the Ligier JS31 holds its own page in a catalogue built to record every car ever made, from series production to one-off concepts.
The record does not fix a firm introduction year for the Ligier JS31, which is itself informative: cars without a clean launch date are usually prototypes, coachbuilt specials, or models whose history was written down long after the fact. The catalogue keeps them anyway, because the odd corners of the record are where the interesting machines hide.
On paper, the Ligier JS31 reads like this: kerb weight is recorded at 525 kg. Every figure above is a manufacturer specification carried by the Wikipedia infobox or the open Wikidata record for this model — nothing on this page is estimated, and where a source is silent the row simply does not appear.
Within Ligier's own catalogue the Ligier JS31 sits alongside the Easymile EZ10, the Ligier JS2, the Ligier JS2 R, the Ligier JS4. The record names the JS29 as its predecessor and the JS33 as its successor, fixing its place in the model line's chronology. Design is credited to Michel Têtu (Technical Director) / Claude Galopin (Chief Designer) / Michel Beaujon (Head of Design).
The Ligier JS31 also has a competition record: 0 recorded wins from 16 starts and 0 championships. A race history changes how a car should be valued — competition machines appreciate on provenance, not depreciation curves.
This library is generated, verified and rebuilt from the open record on every deploy. The catalogue skeleton comes from Wikidata, specifications from Wikipedia's infoboxes under CC BY-SA, photography from Wikimedia Commons under each file's own licence, and the ownership data from United States federal safety records. Nothing is written by hand and nothing is invented: every fact on this page traces to a public source, and every page is rebuilt nightly as those sources improve. Errors in the source record will appear here too — and disappear the night the source is corrected.
Most car databases stop at series production. This one deliberately does not, because concept cars, racing specials and cancelled prototypes are where the industry thinks out loud — the ideas tested in public years before they reach a showroom. Holding them beside the production cars they inspired makes the lineage legible: nearly every landmark road car in this library has a concept ancestor somewhere in the catalogue, and the connections run through the era links on every page.
Some pages in this library brim with specifications; others, like corners of every archive, are thin. The honest response to a thin record is to say so, not to pad it. What is shown here is exactly what the public record supports today — and because the harvest re-runs nightly, the page you are reading is the fullest version of this car's open record that existed the last time the site was built.
A specification sheet is only half a car's story. The other half — what breaks, what it costs to keep, which years to avoid — lives in MotorJury's ownership database, computed nightly from federal complaint and recall records and EPA economy data. Where the Ligier JS31 was sold in the United States, its model years carry full ownership verdicts there.
Specifications come from the Wikipedia infobox for this model (CC BY-SA) and the open Wikidata record, and are shown only where a source actually carries them — nothing here is estimated. Figures are manufacturer specifications, not measured results.
