Lincoln Continental Mark V: A Comprehensive Guide

The Lincoln Continental Mark V, a symbol of American luxury and excess, reigned supreme in the late 1970s. Representing the pinnacle of personal luxury coupes, the Mark V was a statement of wealth and style, offering a blend of comfort, elegance, and imposing presence. This guide provides a detailed look at this iconic automobile, helping potential buyers understand its history, strengths, weaknesses, and what to look for in the current market.

Generations

Fifth Generation (1977-1979)

The Mark V represents the fifth and final generation of the Continental Mark series. It was built on the Ford Thunderbird platform but distinguished itself with uniquely Lincoln styling. The key changes across its relatively short production run include:

1977: Introduced as a completely redesigned model, featuring sharper lines, a bolder grille, and hidden headlamps. It was longer and wider than its predecessor. Key design elements included the "Continental tire" bulge on the decklid (a faux spare tire), and opera windows in the C-pillars. Engine options included the 400 cubic inch (6.6L) and 460 cubic inch (7.5L) V8 engines.

1978: Minor trim changes and detail updates. Focus was on maintaining the popular design and opulent features. The engine options remained the same.

1979: This was the final year of production. Minor interior and exterior cosmetic changes were implemented. The biggest change was the phasing out of the 460 cubic inch engine due to tightening emissions regulations; the 400 remained the only engine option. Collectible Designer Series Editions were particularly popular this year.

Reliability & Common Issues

While the Mark V exuded luxury, its reliability is a mixed bag. The sheer complexity and age of these vehicles mean that potential buyers should be prepared for maintenance and repairs. Here's a breakdown of common issues:

Engine Issues:

400 and 460 V8 Engines: While powerful, these engines can suffer from oil leaks (particularly around the valve covers and rear main seal), vacuum leaks (leading to poor performance and emissions), and carburetor issues (especially in models that have not been properly maintained). The 460 is known for being particularly thirsty, and both engines are susceptible to overheating if the cooling system is neglected.

Timing Chain Slack: On older models, the timing chain can become slack, leading to poor performance and potential engine damage. Listen for a rattling sound upon startup.

Emissions Control Systems: The emissions control systems of this era were complex and often unreliable. Expect potential issues with EGR valves, catalytic converters, and vacuum lines. Repair or replacement can be costly.

Transmission Issues:

C6 Automatic Transmission: The C6 is generally a robust transmission, but can suffer from slipping, hard shifting, and fluid leaks with age and neglect. Regular fluid changes are crucial for longevity.

Electrical Issues:

Vacuum-Operated Accessories: Many features, such as the power windows, door locks, and climate control system, rely on vacuum. Leaks in the vacuum system are common and can cause these features to malfunction.

Wiring Harness Degradation: Over time, the wiring harness can become brittle and corroded, leading to electrical shorts and malfunctions. Check for cracked or damaged wiring, especially in the engine compartment.

Headlight Door Issues: The hidden headlights rely on a complex vacuum or electric motor system that often fails. Ensuring proper operation of the headlight doors is important for both aesthetics and safety.

Body and Interior Issues:

Rust: Rust is a significant concern, especially in areas with harsh winters or coastal environments. Pay close attention to the lower body panels, wheel wells, trunk floor, and around the windshield and rear window.

Vinyl Top Condition: The vinyl top is prone to cracking, fading, and bubbling. Replacing a vinyl top can be expensive.

Interior Wear: Expect to see wear and tear on the leather upholstery, carpeting, and dashboard. Sun damage can be a significant issue, leading to cracked dashboards and faded upholstery. Ensure all interior features, such as power seats and windows, are functioning properly.

Suspension and Steering Issues:

Worn Suspension Components: The suspension system can suffer from worn bushings, ball joints, and shock absorbers, leading to a bouncy ride and poor handling.

Power Steering Leaks: Power steering leaks are common. Check the power steering pump and hoses for leaks.

Driving Experience

Driving a Mark V is an experience unlike any modern car. It's all about comfort and cruising. Here's what you can expect:

Pros:

Smooth Ride: The Mark V offers a exceptionally smooth and comfortable ride, ideal for long highway journeys. The soft suspension soaks up bumps with ease.

Powerful Engine: The 400 and 460 V8 engines provide ample power for effortless acceleration and cruising.

Luxurious Interior: The interior is lavishly appointed with comfortable seats, plush carpeting, and luxurious trim.

Classic Styling: The Mark V is a head-turning classic with its distinctive styling and imposing presence.

Cruising Comfort: Designed for long drives, it offers fatigue-free seating and a quiet cabin.

Cons:

Poor Fuel Economy: Expect very poor fuel economy, especially with the 460 engine.

Large Size: The Mark V is a very large car, making it difficult to maneuver in tight spaces and park in urban environments.

Handling: Handling is not a strength. The Mark V is designed for comfort, not performance. Expect significant body roll in corners.

Maintenance Costs: Due to the car's age and complexity, maintenance and repair costs can be high.

Buying Advice

Purchasing a Mark V requires careful consideration and research. Here's some advice to help you make an informed decision:

What to Look For:

Rust-Free Example: The most important factor is to find a car with minimal rust. Rust repair can be very expensive.

Well-Maintained Car: Look for a car that has been well-maintained, with documented service records.

Original Condition: Cars that are in original condition are generally more valuable.

Functional Accessories: Ensure that all accessories, such as the power windows, door locks, and climate control system, are functioning properly.

Low Mileage (Relatively Speaking): While mileage isn't everything, a lower-mileage car that has been well maintained is generally a better bet.

Years to Consider:

1977: The first year of the generation, offering a clean, fresh design. Finding one well-maintained can be rewarding.

1978: Very similar to the 1977 model, making it a good option if you can find one in excellent condition.

1979: The final year, and especially the Designer Series Editions are considered highly desirable and collectible.

What to Avoid:

Cars with Significant Rust: Avoid cars with extensive rust, as repair can be very costly.

Cars with Extensive Modifications: Cars that have been heavily modified may be difficult to repair and maintain.

Cars with Neglected Maintenance: Avoid cars that show signs of neglected maintenance, such as oil leaks, worn tires, and a dirty interior.

Cars with Electrical Issues: Complex electrical problems can be very difficult and expensive to diagnose and repair.

Final Thoughts:

The Lincoln Continental Mark V is a classic American luxury car that offers a unique driving experience. If you are prepared to deal with the potential challenges of owning an older vehicle, a well-maintained Mark V can be a rewarding and enjoyable classic to own. Thorough inspection and research are key to finding a good example.
