The 1978 Lincoln Continental Mark V is one of the last true American land yachts. It represents a time when size, comfort, and luxury were the main ingredients in building a dream car. With its long, flat hood and signature opera windows, the Mark V was never meant to blend in.
This car wasn’t just about looks. It also introduced features that were way ahead of its time, especially for the late 1970s. For collectors, enthusiasts, or anyone who appreciates vintage American muscle with luxury touches, this car holds a special place.
When the 1978 Mark V Ruled the Roads
The 1978 model was the final year of the fifth-generation Mark series, produced between 1977 and 1979. That year also marked the end of an era this was the last Lincoln to offer the massive 460 cubic inch (7.5L) V8 engine.
At a time when gas prices were rising and regulations were tightening, Lincoln went all-in with luxury and size before downsizing took over. The 1978 version came fully loaded and was marketed as the peak of American personal luxury coupes.
How the 1978 Lincoln Mark V Balanced Style and Tech
You might think a big old cruiser like this would be all show and no brains, but the Mark V actually packed some impressive technology for its time. It came with automatic climate control, a digital “miles-to-empty” readout, and an optional automatic headlamp dimmer that adjusted your high beams based on traffic.
Power everything was the norm windows, seats, antenna, and even the trunk release. A Cartier-branded dashboard clock reminded you that this wasn’t your average highway car. You could even upgrade to a Quadraphonic 8-track stereo system for high-quality sound in all four corners of the cabin.
Understanding Fuel Economy and Engine Options on the Mark V
The Mark V came with two engine options. The standard was a 400 cubic inch (6.6L) V8, and the optional upgrade was the 460 cubic inch (7.5L) V8. Both were paired with a smooth-shifting 3-speed automatic transmission.
| Engine | Displacement | Horsepower | Estimated MPG |
|---|---|---|---|
| 400 V8 | 6.6L | ~166 HP | 13–15 highway |
| 460 V8 | 7.5L | ~210 HP | 10–12 highway |
Neither engine was fuel-efficient by modern standards, but at the time, it was the trade-off for power and a smooth, quiet ride.
What the 1978 Lincoln Continental Mark V Cost in Showrooms
Back in 1978, the Mark V started at around $11,000. That might not sound like much today, but adjusted for inflation, that’s over $50,000 in today’s money. With options like leather interiors, power sunroofs, and special edition designer trims, the price could easily climb over $16,000.
Lincoln also offered limited-edition designer packages with interior and exterior colors chosen by top fashion names like Cartier, Bill Blass, Givenchy, and Emilio Pucci. These versions were some of the most stylish and are among the most collectible today.
Common Mistakes With the 1978 Mark V and How to Avoid Them
One common mistake people make is thinking this car is just a gas-guzzling boat with no real value. In truth, well-preserved examples are going up in value, especially the designer editions.
Another issue is ignoring hidden rust spots, especially under the vinyl roof, wheel wells, and lower body panels. These areas can become expensive problems if not addressed early.
Many buyers also underestimate the cost and time needed to find original parts. While the engines are tough, trim pieces, electronic parts, and special badging are getting harder to locate.
Best Tips to Maintain and Enjoy a 1978 Lincoln Mark V
Look for cars with low mileage and full maintenance records. These vehicles were often bought by older owners who kept them in garages and drove them gently.
Join Lincoln owner forums and classic car clubs for help with sourcing parts, manuals, and advice. Keeping the suspension in good shape is key to preserving that legendary ride quality.
Use a good quality car cover if it’s stored outdoors, and keep the vinyl top treated and clean to avoid cracking or fading. If you’re planning a restoration, focus on keeping original details intact—aftermarket modifications can hurt value.
Conclusion
The 1978 Lincoln Continental Mark V is more than just a vintage car. It’s a symbol of the final era of full-size American luxury, combining massive size, bold styling, and surprising tech features.

For collectors or anyone who loves old-school American craftsmanship, the Mark V offers a rewarding experience, both behind the wheel and in the garage.
