The Sunshine Special was the official state car used by Franklin D. Roosevelt, the 32nd President of the United States. It is said to have been the "First Presidential car to acquire its own personality". It was a 1939 twelve-cylinder engine, four-door convertible originally built by Lincoln and was specifically modified for the President by a speciality coach builder, Brunn & Company, Inc., in Buffalo, New York, at a cost of $4,950 (the original cost of the car was $8,348.74). Initially called "Old 99," in reference to a number on its first license plate, it was later nicknamed the "Sunshine Special" (the exact origin of the nickname is unknown, but it was most likely first used in a photo caption) as a reference to its retractable roof, and was famously enjoyed by the president, who had its roof brought down during public gatherings. At other times, the car was used as traditional presidential transportation. This was in spite of a previous assassination attempt against Roosevelt as he was riding in a Buick convertible, prior to the creation of the Sunshine Special.
The Sunshine Special was originally a Lincoln K-series built by the Lincoln division of Ford, and modified by Brunn & Company to U.S. government specifications. It was powered by a 150hp, 414 cubic inch V12 L-head engine. The limousine was originally equipped with a siren, running lights, and a 2-way radio, as well as extra-wide running boards and grab handles for Secret Service agents. The vehicle had a convertible roof, hence the reasoning for the car's nickname. The car quickly became known as a favorite of the president, who was a victim of polio and used a wheelchair. With the convertible top down Roosevelt sometimes appeared before crowds without actually leaving the vehicle. There are newsreels of the time showing the car being driven on stage, such as at the podium constructed for a campaign appearance at Ebbets Field in New York in 1944.
