Lincoln Continental Mark IV: A Comprehensive Guide
The Lincoln Continental Mark IV is a personal luxury coupe produced by Ford Motor Company and marketed under the Lincoln brand from 1972 to 1976. Representing the fourth generation of the Continental Mark series, it followed the Mark III and preceded the Mark V. During its production run, it was one of the best-selling personal luxury coupes in the American market, rivaling the Cadillac Eldorado.
Generations
1972-1976: Lincoln Continental Mark IV
- Key Changes: This was the sole generation of the Mark IV. It was built on the same platform as the Ford Thunderbird but featured unique styling cues, including a long hood, short deck, hidden headlamps, and a "Continental tire" bulge on the trunk. The interior was appointed with luxury features such as leather upholstery, power accessories, and wood trim.
- 1973: Federally mandated 5 mph bumpers were added to the front and rear. This impacted the overall length of the car.
- 1974: Slight changes to the grille and taillights. The catalytic converter was introduced, requiring unleaded gasoline.
- 1975: Introduction of the "Versailles Edition," a precursor to the standalone Lincoln Versailles model. Emission control systems were further refined.
- 1976: Minor trim changes and increased emphasis on luxury features. Several special edition Designer Series models were offered.
Reliability & Common Issues
While the Lincoln Continental Mark IV is admired for its style and comfort, prospective buyers should be aware of several potential reliability issues. These are generally associated with age and the complexity of the vehicle's systems.
Engine
- 460 Cubic Inch (7.5L) V8: This engine is generally robust, but can suffer from valve guide wear, leading to oil consumption and smoking. Watch out for signs of overheating, as the cooling system can be prone to leaks with age. Carbon buildup in the EGR system is also a common issue, especially in later years with more stringent emissions controls.
- Fuel System: Carburetor problems are common, particularly with the Motorcraft 4300D. Rebuilding is often necessary, and quality rebuild kits are essential. The fuel pump and fuel lines can also deteriorate over time, leading to fuel leaks and poor performance.
Transmission
- Ford C6 Automatic Transmission: A strong transmission, but proper maintenance is critical. Check for smooth shifting and any signs of slipping. Fluid leaks are common from the front and rear seals, as well as the valve body. Regular fluid and filter changes are essential for longevity.
Suspension & Brakes
- Front Suspension: Ball joints and tie rod ends are wear items and should be inspected regularly. The front coil springs can sag over time, affecting ride height and handling.
- Rear Suspension: Leaf springs can also sag, although they are generally more durable than the front coils. Shock absorbers should be replaced as needed to maintain ride quality.
- Brakes: Power-assisted disc brakes were standard. Check for leaks in the brake lines and master cylinder. Calipers can seize due to corrosion. Replacement parts are generally available, but can be expensive.
Electrical System
- Wiring: The wiring harnesses in these cars are known to become brittle and corroded with age, leading to electrical problems such as intermittent lights, malfunctioning power windows, and charging system issues. Carefully inspect wiring for damage.
- Vacuum System: Vacuum lines control many functions, including the headlamp doors, climate control, and power door locks. Leaks are common and can cause a variety of problems. A vacuum diagram is essential for troubleshooting.
- Power Windows and Locks: The power window and lock systems can be problematic due to wear in the motors, switches, and linkages. Repairing these systems can be time-consuming.
Body & Interior
- Rust: Rust is a major concern, especially in areas with harsh winters. Check the lower body panels, floor pans, trunk, and around the window frames for signs of corrosion.
- Interior: The interior trim can be fragile and prone to cracking and fading. The leather upholstery can also show wear and tear. Replacement parts can be difficult to find and expensive.
Driving Experience
The Lincoln Continental Mark IV prioritizes luxury and comfort over sporty handling. It offers a smooth and quiet ride, making it an excellent cruiser for long distances. The powerful 460 V8 provides ample torque for effortless acceleration. However, the car's large size and weight can make it feel cumbersome in tight spaces.
Pros:

Cons:
- Large size and weight
