Lagonda LG45 / V12

W.O. Bentley's post-Bentley masterwork — six-cylinder LG45 and the sublime 4½-litre V12, including a third place at Le Mans 1939.

Overview

Why this car matters

After the Bentley collapse, W.O. Bentley joined Lagonda in 1935 as technical director. The LG45 used a developed Meadows 4,453cc six, while the all-new Lagonda V12 — entirely W.O.'s work — was a 4,480cc 60-degree V12 producing around 175 bhp, with double-overhead camshafts and remarkable refinement. A V12 finished third at Le Mans in 1939. Coachwork by James Young, Frank Feeley and others gave the cars elegant, restrained pre-war lines.

Some of the most technically advanced pre-war British engineering, by the same hand that designed every important Bentley before it.

Buyer's Guide

What to look for

Provenance and originality

For pre-war and vintage cars such as the Lagonda LG45 / V12, 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. Original V12 engine, sporting open coachwork, W.O. Bentley provenance and recognised club registration.

Mechanical inspection priorities

The V12 is sophisticated and rewards a recent specialist rebuild; the LG45 Meadows six is robust if maintained. 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.

Body, chassis and originality of coachwork

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.

Specification and event eligibility

Le Mans-style short-chassis V12 Rapide and James Young drophead coupes lead values; saloons offer the V12's refinement at a discount. 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.

Ownership

Living with it

Typical mileage
300–2,000 miles typical for vintage use; rally cars higher
Service interval
Annual full service; pre-event check before any rally or tour
Annual running cost
$8,000 – $35,000 depending on use, storage and event programme
Fuel economy
10–18 mpg typical; heavy carburetted engines run rich
Insurance
Use a specialist agreed-value vintage policy with declared value reviewed annually. Premiums reflect declared value, storage, event use and driver experience with pre-war machinery.

Maintenance planning

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.

Specialist access and parts

A small UK specialist network handles V12 work; engine parts are individually fabricated. 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.
