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.
