The Ford Thunderbird was a car manufactured in the United States by the Ford Motor Company. It entered production for the 1955 model year as a two-seater sporty car but, unlike the similar Chevrolet Corvette, the Thunderbird was never sold as a full-blown sports car. Ford described it as a personal luxury car, a description which named a new market segment. In 1958, the Thunderbird gained a second row of seats. Succeeding generations became larger until the line was downsized in 1977 and again in 1980. Sales were good until the 1990s, when large 2-door coupes became unpopular; production ceased after 1997. In 2002, a revived 2-seat model was launched, which was available through the end of the 2005 model year.
