Specifications for the 1931 Ford Model A Roadster

by John Stevens J.D.

After a 23-year absence, Ford brought back the Model A to replace the Model T. This second generation was produced from 1927 through 1931. In 1931, 19 body types were produced under the Model A brand, including the two-seat Roadster. The Coupe and the Deluxe Coupe were the only other Model As in 1931 that featured two doors. Despite its lower price, the Coupe and the Deluxe Coupe outsold the Roadster by significant margins. Ironically, it is because of the Roadster's poor sales that its value has steadily increased due to its rarity.
