The Ford Mustang was brought out five months before the normal start of the 1965 production year. The early production versions are often referred to as “1964½ models” but all Mustangs were advertised, VIN coded and titled by Ford as 1965 models, though minor design updates for fall 1965 contribute to tracking 1964½ production data separately from 1965 data. with production beginning in Dearborn, Michigan on March 9, 1964; the new car was introduced to the public on April 17, 1964 at the New York World’s Fair.
More than 125 members of the media gathered at the Ford Pavilion at the New York World’s Fair for a preview of the cars that would be on display. Then-Ford Motor Company Vice President Lee Iacocca delivered a speech that discussed the emerging market of younger drivers born in the years after World War II. All of this was prelude to the unveiling of the all-new 1965 Ford Mustang. The sporty car officially went on sale four days later and was an instant sensation, with more than 22,000 sold on opening weekend and nearly 420,000 units in the first year.
