The Continental Mark IV is a personal luxury car that was sold and marketed by the Lincoln division of Ford Motor Company from the 1972 to 1976 model years. The third generation of the Mark series, the Mark IV grew in size over its Continental Mark III predecessor and its Cadillac Eldorado rival. Sharing a common chassis with the Ford Thunderbird, the Mark IV was given its own exterior design from the windows down, returning hidden headlights, a radiator-style grille, and a Continental spare tire trunklid.
