Not every car that is designed, produced, and sold to the public becomes a success. In reality, automotive manufacturers are just as likely to release a failure as they are to create a hit.
From unattractive designs and flawed engineering to outright lemons that drive customers away, the history of the automobile is filled with some truly regrettable models.
Many of these vehicles have earned lasting notoriety and remain etched in the minds of the public for all the wrong reasons.
Below is a list of 10 of the worst cars ever built and sold.

10. Lincoln Continental Mark IV
When people refer to 1970s cars as “boats,” they are likely thinking of the Lincoln Continental Mark IV.
Frequently seen in films set in that era, this massive vehicle was long, sluggish, and far from practical. Despite its drawbacks, it was marketed as a luxury car in the 1970s, even featuring a shag-carpeted interior.

However, the Lincoln Continental Mark IV was notorious for its frequent mechanical issues and exorbitant fuel costs.
Over time, both the public and the press began calling it a “hunk of junk.” And just imagine trying to parallel park this behemoth yikes!
9. Reliant Robin
To be fair, it was probably inevitable that a company would eventually design a car with only three wheels. That company turned out to be the Reliant Motor Company in England, which introduced the three-wheeled Robin in 1973.
While the car never achieved the mainstream success its creators had hoped for, Reliant continued producing various versions of the Robin for three decades, until 2003.
This longevity was largely due to the car’s cult following among certain British motorists who were willing to overlook its major stability issues.

With just a single wheel in the front, the Reliant Robin had a notorious tendency to tip over when taking a turn at speeds above 25 miles per hour or when angled at 45 degrees.
It wasn’t uncommon to see drivers on the side of English roads struggling to push their toppled Robins upright again. Despite its flaws, the Reliant Robin was also a pioneer in automotive design it was the first car ever manufactured with an entirely fiberglass body.
8. PT Cruiser Convertible
The PT Cruiser never became the success Chrysler had envisioned. In fact, the car earned the unflattering nickname “PT Loser,” largely due to its oversized, boxy appearance that failed to capture any real sense of style. Even its name PT, short for “Personal Transport” was uninspiring.
However, if there was one version of this vehicle that people disliked even more than the original, it was the convertible model.

In a desperate attempt to inject some appeal into the PT Cruiser before discontinuing production in 2010, Chrysler introduced a convertible version in 2005. The result? Both critics and the public despised it.
The car essentially looked like a standard PT Cruiser with the roof unceremoniously chopped off. This is a prime example of a design flaw overpowering everything else about a vehicle. Not cool, Chrysler. Not cool.

7. Chrysler K-Car
Yet another misstep from Chrysler, the K-Car specifically the Plymouth Reliant and Dodge Aries became the very definition of “cheap” and played a major role in solidifying Chrysler’s 1980s reputation for producing subpar vehicles.
Designed under the leadership of Chrysler’s then-CEO Lee Iacocca, the K-Car was meant to be an affordable, mass-market vehicle that would appeal to the average consumer and help rescue the struggling company.

In that regard, it succeeded both models sold over a million units in their first year of production, and Motor Trend even named the K-Car its Car of the Year in 1981.
Despite these early achievements, the K-Car quickly earned the nickname “Poor Man’s Car” and became infamous for a range of issues, including knobs that literally fell off, unreliable transmissions, and bodies that rusted out far too quickly.
A budget car built with budget materials, the K-Car has since become a symbol of 1980s nostalgia and automotive history—for all the wrong reasons.
6. BMW X6
BMW has made relatively few mistakes over the years. However, with the X6 model, the German automaker seemed to have taken a significant misstep.
The main issue with this vehicle is that consumers have struggled to classify it. Is it a sport utility vehicle, a luxury car, or some kind of unusual hybrid? There has been considerable confusion surrounding its identity.
In an effort to market the X6, BMW attempted to introduce an entirely new category, dubbing it a “Sport Activity Vehicle,” or SAV for short.

According to BMW executives, this model was designed to offer the driving experience of a sedan while maintaining the toughness of an off-road vehicle.
Unfortunately, the public did not embrace the concept, and both the X6 and the SAV classification failed to gain widespread popularity.
A second generation of the X6 was unveiled at the 2014 Paris Auto Show, featuring a design that closely resembled a conventional SUV, or sport utility vehicle. However, whether this latest version can change the fate of the X6 remains uncertain.
5. DeLorean DMC-12
The DeLorean DMC-12 sports car will always be associated with the Back to the Future film franchise, remembered fondly as the time machine that allowed lead character Marty McFly (Michael J. Fox) to travel through time.
However, what many moviegoers overlook is that the DeLorean DMC-12 was originally intended to be a joke in the film. The car’s mere presence on screen was meant to be humorous due to its infamous history.
The DMC-12 was the only model ever produced by the DeLorean Motor Company, which was founded in 1975 but filed for bankruptcy and shut down by 1982.

Created by the unconventional automobile executive John DeLorean, the company’s flagship vehicle was a massive failure, largely due to its stainless steel body and gull-wing doors.
Additionally, the car was equipped with an underpowered engine that required more than 10 seconds to accelerate from 0 to 60 miles per hour.
Automotive critics were highly critical of the vehicle, and with a hefty price tag of $25,000 in 1977, it was deemed too expensive for most consumers.
It wasn’t until the DMC-12 appeared in 1985’s Back to the Future and its sequels that the public began to view the car with nostalgia and appreciation.
4. AMC Gremlin
Introduced in 1970, the Gremlin was the car that every teenager wished their parents didn’t own.
It was a clear attempt by American Motors Company to beat Ford and General Motors to the subcompact car market, but it ultimately became one of the most notoriously unattractive cars in automotive history.
With a long, low front end and an abruptly shortened hatchback rear, the Gremlin appeared oddly proportioned from every angle.

Beyond its questionable design, the Gremlin was cheaply built and poorly engineered. It came equipped with vacuum-operated windshield wipers, a heavy six-cylinder engine, and unpredictable handling due to the loss of suspension travel in the rear.
While the Gremlin did have the advantage of being faster than other subcompact cars of its time, that provided little comfort to those who had to drive it and endure the relentless jokes that came with owning one.
3. Peel Trident
Resembling something straight out of The Jetsons cartoon, the Peel Trident is one of those futuristic oddities from the 1960s that never quite lived up to its promise.
Designed and manufactured on the Isle of Man in 1966, the Trident measured only four feet, two inches in length, earning it the distinction of being the world’s smallest car.
Unfortunately, that was its only real achievement, as the vehicle was utterly impractical in nearly every other way.

The Trident’s Plexiglas roof intensified sunlight, effectively baking anyone brave enough to drive this tiny, peculiar-looking machine.
On top of that, it was notoriously difficult to maneuver and frustrating to park. Space was another major issue there was barely enough room for a single occupant. And then there was the name Trident.
Isn’t that the three-pronged weapon wielded by the King of Atlantis? The whole concept was just plain bizarre.
2. Yugo
The Yugo is, without a doubt, the mother of all lemons. This disaster on wheels was imported into the United States from Soviet-controlled Yugoslavia in the mid-1980s as an affordable option for budget-conscious Americans.
However, the car was so cheaply made and poorly assembled that even the marketing brochure listed “carpet” as a standard feature hardly a selling point.

Reliability was virtually nonexistent. The Yugo was infamous for breaking down so often that it even featured a rear window defroster not to clear frost, but supposedly to keep people’s hands warm while they pushed it.
Seriously. The engines had a tendency to explode, the electrical system frequently short-circuited, and parts would randomly detach without warning.
The car was so notoriously unsafe and unreliable that many insurance companies outright refused to cover it. Given its abysmal reputation, it’s no surprise that the Yugo’s time in the American market was brief.
1. Ford Pinto
Still a favorite target of jokes, the Ford Pinto remains one of the most infamous cars ever made.
First introduced in 1971, the Pinto gained notoriety for its alarming tendency to burst into flames during low-speed rear-end collisions making it not only a serious safety hazard but also frequent fodder for late-night comedians.
What truly cemented the Pinto’s disgraceful legacy, however, was a now-infamous internal memo from the Ford Motor Company.

This document detailed a cost-benefit analysis that determined it would be cheaper to pay an estimated $50 million in victim settlements than to recall the cars and reinforce their rear ends, which would have cost the company $120 million.
Dubbed the “Pinto Memo,” this revelation became a lasting symbol of corporate greed and cold, profit-driven decision-making. No matter how one looks at it, the Pinto remains a massive debacle in automotive history.
