The Lincoln Continental Mark IV was a luxury car at the top end of the personal luxury car market sold under the Lincoln brand of the Ford Motor Company in North America between 1972 and 1976. It replaced the successful Continental Mark III, and was in turn replaced by the Continental Mark V. The Mark IV and the contemporary Ford Thunderbird were built on a common platform at the same plant in Wixom, Michigan, and were alike in most major respects. For the 1977 model year it was replaced by the Mark V, which kept similar dimensions and internals but featured updated straight-edged styling.
