The Ford Thunderbird (colloquially called the T-Bird) is a personal luxury car manufactured and marketed by Ford from model years 1955-2005 (with a 1997-2002 hiatus) across 11 generations. Introduced as a two-seat convertible, the Thunderbird was offered variously as a four-seat hardtop coupe, four-seat convertible, five-seat convertible and hardtop, four-door pillared hardtop sedan, six-passenger hardtop coupe, and five-passenger pillared coupe, with the final generation designed again as a two-seat convertible.
