The Oldsmobile Model D is a car from Oldsmobile, built from 1909, when a car was a rich man's adventure and every maker was a workshop. Under the bonnet: NNN cuin.
The story
The Model D was a four-seat passenger car produced by General Motors under the Oldsmobile brand in 1909, replacing the Model M. It was the last car engineered by Oldsmobile before it became a division of GM and began sharing a platform with Buick.

Its place in the line
Its family tree is legible: it took over from the Oldsmobile Model M; assembly was at Lansing, Michigan (Lansing Car Assembly), United States. Its contemporaries in the catalogue — the Ford Model T, the GM (General Motors) Marquette, the Fiat S61 — show what else the money bought that year. Nearby in the Oldsmobile catalogue sit the Oldsmobile 442 and the Oldsmobile 88.
What it costs now
MotorJury scores cars on the United States complaint and recall record, and the Oldsmobile Model D has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
