Following the successful redesign of the Lincoln Continental for the 1970 model year, Ford Motor Company chose an evolutionary design path for the successor of the Continental Mark III. With designers again using sharp-edged fenders, hidden headlamps, and a tall radiator-style grille, the Continental Mark IV retained the traditional "long-hood, short deck" coupe proportions of the Mark III along with its "Continental spare tire" decklid. The spare tire was actually stored on a ledge in the trunk on top of the gas tank, immediately behind the rear seat.
