Demi-Tonneau
Chassis #: 50361
Sold for $99,000 at 2005 Vintage Motor Cars at Amelia Island.
Sold for $79,200 at 2010 RM Auctions - Vintage Motor Cars of Meadow Brook.
Demand for Cadillac's had risen by 1910, so much so that the company was pre-selling all seven models, and in 1911, production reached a new record of 10,019 cars. 1911 would be the final year for the Demi-Tonneau, which allowed quick conversion from a four-seat touring car to a stylish two-seat runabout. It was priced at $1,700, which was identical to that of the Roadster and the standard Touring car. Standard equipment on the Model 30 included hand-buffed leather upholstery, a Delco ignition and a Bosch magneto, gas headlamps and a gas generator, a pair of side oil lamps, a tail lamp, a horn, a tool set and a tire repair kit. 1911 would be the last year any Cadillac would be fitted with gas headlamps and oil lamps.

Cadillac increased is standard L-head four-cylinder engine to 286.3 cubic-inches for 1911, resulting in a power increase from 28.9 to 32.4 A.L.A.M. horsepower. This example has been restored before it was acquired by the current owner in 2005. It is finished in a blue body, black fenders and a light grey chassis, running gear and wheels. There are a black button-tufted leather seats and a black canvas top. There is a full set of Gray and Davis side lamps, headlamps and a tail lamp. Other equipment includes a New Haven clock, a 70-mph Cadillac speedometer, a folding windshield and all-white tires.

In 2010, this Demi-Tonneau was offered for sale at the Vintage Motor Cars of Meadow Brook where it was estimated to sell for $80,000 - $100,000. As bidding came to a close, the car was sold for the sum of $79,200 including buyer's premium.
