Cadillac's V16 — America's first production sixteen-cylinder, with bespoke Fleetwood coachwork.
Cadillac launched its V16 in 1930, becoming the first American manufacturer to offer a production sixteen-cylinder engine — a 7,406cc 45-degree OHV V16 producing 165 bhp. Coachwork was supplied almost entirely by Fleetwood (Cadillac's in-house custom shop), with body styles ranging from formal limousines and town cars to dual-cowl Phaetons and convertible coupes. Approximately 4,400 of the OHV V16 were built between 1930 and 1937, after which a simpler 135-degree side-valve V16 (1938–1940) replaced it.

| Variant | Years | Production | Notes |
|---|---|---|---|
| OHV V16 (Series 452) | 1930–1937 | — | 7.4-litre OHV V16; the desirable specification. |
| Side-valve V16 (Series 90) | 1938–1940 | — | Simpler 135° side-valve V16; less desirable. |
For pre-war and vintage cars such as the Cadillac V-16 Series 452, provenance is paramount. Chassis and engine number matching, period coachbuilder records, factory build sheets where available, continuous ownership documentation, original handbooks and any competition or concours history are the foundation of value. Body style (open > closed), Fleetwood coachwork, CCCA Full Classic status, continuous history.
The OHV V16 is sophisticated and refined; carburation and ignition are standard service items. Strong CCCA support. A pre-purchase inspection by a recognised marque specialist should include compression and leak-down testing, magneto and ignition checks, chassis straightness and frame survey, axle and steering wear assessment, brake system review (mechanical or hydraulic per period), and an extended road test on varied terrain to expose carburation, cooling and gearbox issues that only emerge under sustained running.
Pre-war coachwork is rarely truly original after a century of use. Establish whether the body is original to the chassis (period photographs, build records, coachbuilder plates), whether it has been re-bodied at any point, and the standard of any restoration. Quality of timber framing, ash health, panel beating and paint depth are all critical. Concealed structural rot, re-bodies presented as original, and 'tribute' cars built on later or unrelated chassis must be priced accordingly.
Fleetwood dual-cowl Phaetons, roadsters and convertible coupes lead values; closed bodies trade more modestly. For vintage cars, event eligibility — Mille Miglia, Goodwood Revival, Pebble Beach, VSCC events, Le Mans Classic — can underwrite a substantial proportion of market value. Verify FIA/FIVA papers, period race history where claimed, and the car's standing with the relevant marque registry before purchase.
Regional ranges authored independently — each reflects its local market, not an FX conversion
Vintage cars require disciplined preventive maintenance: lubrication regimes, magneto service, carburettor synchronisation, brake adjustment, and timber and trim conservation. A car used regularly and serviced annually by a specialist will outlast a stored example neglected for decades.
Strong CCCA and Cadillac La Salle Club support; specialist mechanical and coachwork shops across the US. Confirm the availability of marque specialists, period-correct fasteners, coachwork trim, instruments and tyres before committing. A car requiring fabricated one-off parts will absorb time and cost that a similar example with active specialist support will not.
