Cadillac Model 30 Demi-Tonneau

Cadillac was less than a decade old when this 1911 Cadillac Model 30 Demi-Tonneau was built, but the marque had already established itself as a builder of high-quality automobiles. By 1910, demand was so high that Cadillac was pre-selling all seven models, and in 1911, production reached a new record of 10,019 cars.

Alas, the times were changing, and 1911 was the final year for the Demi-Tonneau, which allowed quick conversion from a four-seat touring car to a stylish two-seat runabout. Its $1,700 price tag was identical to that of the Roadster and the standard Touring car. Standard Model 30 equipment 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. Although standard on most of the Model 30 range, 1911 would be the last year any Cadillac would be fitted with gas headlamps and oil lamps.

This car was auctioned off by RM Auctions in July of 2010 at the Shotwell Gustafson Pavilion at Meadow Brook Hall, Rochester, Michigan.
