1931 Cadillac V-12 Series 370A Roadster

The 1931 Cadillac V-12 Series 370A roadster gives the twelve-cylinder Cadillac a compact, open passenger body. The selected Greenwich concours photograph identifies the V-12 model directly and shows the two-door body clearly. It provides a sounder illustration than an earlier candidate whose generic roadster caption did not establish whether the car used twelve or sixteen cylinders.

History, identity and design

In the photograph, pale bonnet panels sit above dark wings, while red wheel centres introduce another colour accent. The raised fabric roof outlines a small cabin behind the long engine compartment. A side-mounted spare wheel, circular lamps and bright radiator surround create the familiar layered front of a period luxury car. The important observation is how compact the passenger body looks beside that front structure. The roadster’s visual character comes from the relationship of those parts, not simply from a cylinder-count badge or a modern description of sportiness.

The V-12 roadster is a distinct catalogue subject from the V-16 roadster. Similar body proportions can make casual identification difficult, especially in a small photograph. Here the dated own-work image explicitly identifies a 370A V-12, and the body’s open two-door form is visible. A second primary event record establishes the period 370A roadster designation through a documented participating car. That event car’s family restoration story is not transferred to the different example in the bundled photograph.

The early Series 370 engine-number range is used as a parent ceiling, covering the stated 1930–31 programme. It leaves the exact 1931 roadster production field unset. This approach keeps the numerical rarity claim narrower than an unsupported body total and wider than an arbitrary handful of surviving cars. A surviving-car census answers a different question from original manufacturing output. Both can be useful in a collection, but they should remain separately labelled.

As visual interpretation, the raised roof gives the roadster an unusually clear boundary between mechanical length and passenger shelter. The front wings remain broad and sculptural, while the roof creates a quieter upper shape. Collectors can use those details to compare roof construction, body outline and wheel equipment with dated photographs. Engine identification and body tags still matter, particularly where a restoration has changed trim or colour. This profile celebrates the V-12 roadster’s specific form without claiming that an exterior image can prove a complete original specification.

Specifications and production scope

Keeping the collector record useful

A useful V-12 file separates the model story from the life of an individual vehicle. Record the body or edition designation exactly as it appears in matching documents, then keep clear front, side, rear and cabin photographs with the dates attached. Changes made during restoration deserve their own entries, including the reason for the work and the evidence used. That approach lets future readers compare the physical car with this profile without confusing a present appearance, an original factory specification and an attractive historical association.

Documentary photograph

1931 Cadillac V-12 Series 370A Roadster. Documentary model photograph; individual car provenance is certified only where separately stated in the article. The source image was checked for the pictured body or physical project and its file-specific reuse terms. The visible photograph caption links the photographer, original file and licence so the illustration can be traced independently of the article.

Frequently asked questions

Why replace the first roadster photo candidate?

Its caption did not establish the required V-12 identity. The selected dated concours photograph explicitly identifies a 1931 Cadillac 370A with V-12 engine and shows the matching compact open body.

Is the Cobble Beach restoration history this car’s history?

No. That primary event record documents another participating 370A roadster. It supports the body designation, while its individual ownership and restoration account stays with the car described there.

What production scope applies to the 1931 V-12 Series 370A Roadster?

A conservative ceiling of 5,733 within the 1930–31 Series 370 V-12 engine-number range. Exact output for this body is not established. Shared parent ceilings are non-additive, and numbered positions are not certified completed body totals.

What should a collector document on an individual example?

Keep the vehicle’s identification, body or edition evidence, dated photographs and restoration records together. This V-12 profile explains the model subject; ownership, original finish and present condition require records that match the individual car being considered.

Does this profile provide a complete original specification?

The specification table records the supported identity and engineering context for this year. An exterior photograph cannot establish every optional feature or later component change. Preserve any matching build record before adding more precise equipment claims to the V-12 Series 370A Roadster file.

Who took the photograph and how may it be reused?

The bundled image is credited to Kevauto, under CC BY-SA 4.0 on its individual Commons file page. Keep the visible named credit and licence link. The supplied source version has no local image edits; background signage and photographer marks remain where present.
