The LG.6 and V12 debuted to great acclaim at the 1937 Earls Court Motor Show, and went on sale the following year. Like its big brother, the LG.6 was available in different chassis lengths, and with a number of open and closed body styles on offer–among the cataloged were open Tourer and Drop Head Coupé, partially open Sedanca de Ville and closed Saloon–the cars ranged in weight from 4,000 to more than 5,000 pounds.

These new Lagondas were world-class luxury cars with the modern power and tractability to ensure they were competent in any situation, like their more expensive Rolls-Royce and Bentley counterparts. This marque traded on its famous technical director’s good name, their spiral-bound 1939 showroom brochure’s cover reading “Lagonda Cars for 1939 by W.O. Bentley.”

Bentley was no stranger to Le Mans, and his V-12 proved its competition mettle in France in 1939, with the two V12s entered taking first in category, third and fourth overall places. Indeed, a better-prepared entry was planned for the 1940 Le Mans endurance race, which the war precluded. The V12 was also a prestigious sales success, with 185 examples built. The less expensive LG.6 was a slower seller, only 82 having left the Staines factory before World War II curtailed automotive production in 1940; of them, 67 LG.6s rode on the short 127½-inch chassis, while 18 used the long 135½-inch chassis. 50 LG.6s are known to survive.
