The Lincoln Continental Mark V is a personal luxury coupe that was sold by Lincoln from the 1977 to the 1979 model years. Derived from the same chassis of its Mark IV predecessor, the Mark V was the largest member of the Lincoln Mark series ever produced. With an average of 75,000 units sold in each year available, the Mark V is also the best-selling version of the entire Mark series.
For the 1977 model year, after a five year production run, the Continental Mark IV was replaced by the updated Continental Mark V. In a cost-cutting move, Lincoln chose to re-use the same chassis and underpinnings (also shared with the 1972–1976 Ford Thunderbird).
Using a cancelled Mark IV styling proposal as a starting point, Lincoln-Mercury designers replaced much of the rounded, flared detailing of the Mark IV with sharp-edged “bladed” fenders; the theme carried over into the greenhouse with a squared-off roofline. Styling cues unique to the Lincoln division (concealed headlights, oval opera windows and classic revival radiator grille) and the Continental Mark series (simulated trunklid “spare tire hump”) were retained. To aid engine cooling, the Mark V gained functional fender louvers. By: wikipedia
