VIN: 54261
The open-body Tonneau was one of the first Cadillac automobiles, and the Model 30 was named so for
its 30 horsepower. They were equipped with four-cylinder engines with individually cast cylinders
encased in copper water jackets, making the engine gleam. They sold well and were offered in three
body styles—the Roadster, Tourer, and the Demi-Tonneau with a detachable tonneau that could be
converted into a Runabout. They had a sweeping cowl with a wooden dashboard and an optional
windshield. Almost 67,000 were sold by the time the Model 30 was phased out in 1914.
A meticulous, five-year, complete restoration has just been completed on this very rare and
desirable 1911 Cadillac Model 30 with no expense spared. The chassis was sandblasted and painted in
a French grey enamel. Running boards were fabricated, and a hard-to-find brass Gray & Davis carbide
generator has been mounted. Gray & Davis 107 headlights were also restored and mounted to
painstakingly straightened and restored front fenders along with brass carbide side lanterns. The
rear end has been restored along with the steering. Sean Brayton completed an engine rebuild. The
body has been repainted in factory-correct blue and pinstriped. Loren Burch restored the upholstery
with fine diamond tufting. The correct speedometer and mounting bracket have been fitted to the
cowl along with a folding Troy windshield. The complete drivetrain was unfrozen, repaired, and has
been restored. A correct triple-twist horn has been polished and connected, and the required bracket
reproduced. Among many other tedious jobs, the correct steering box was located and restored before
fitting. She’s completed with correct cream tires. This is absolutely the finest 1911 Cadillac
Demi available today.
CADILLAC
In 1902, Henry Ford left the Henry Ford Company with several of his key partners. With Henry M. Leland of Leland &
Faulconer Manufacturing Company, they began manufacturing automobiles with Leland’s
single-cylinder engine. They named this venture Cadillac Automobile Company after the French explorer who founded
Detroit in 1701, Antoine Laumet de La Mothe, sieur de Cadillac, and based the logo on his coat of arms. This made
Cadillac among the first automotive brands in the world, and they immediately began producing 10 HP horseless carriages
called Runabouts and Tonneaus that were almost identical to the Ford Model A. Because of their precision
manufacturing and reliability, Cadillac quickly accumulated orders and in 1905, merged with Leland to form the
Cadillac Motor Company. By 1906, they were the first volume manufacturer of a fully enclosed car and gained
international notice as the awards for interchangeability and reliability began to pile up.
It’s no wonder that General Motors took notice of America’s premier luxury car maker and purchased it
in 1909. Together, they founded the mass production of automobiles and many innovations, including the first full
electrical systems, Synchro-Mesh manual transmission, the first mass-produced automatic transmission, steel roofs,
dual-plane crankshafts, and shatter-resistant glass. Of the three engines they developed, the V8 set the standard. They
would go on to make more than large luxury vehicles, producing limousines, military vehicles, ambulances, and even
hearses. In the midst of the Great Depression, they introduced the iconic V-16 engine, and sales bounced back and then
some by 1940.
To this day, Cadillac automobiles, a pinnacle of GM’s 2.7 million vehicles sold in 2024, remain a global brand of
luxury.
