Design trends come and go, but some features from classic cars feel like they belong in an entirely different automotive universe. Back when innovation didn’t always need a focus group, automakers experimented with wild, niche, and sometimes oddly brilliant features. Some stuck. Most didn’t. But the ones that didn’t often became legendary.From extravagant styling cues to bizarre functionality, these bygone features are, for the most part, extinct. They didn’t evolve into modern counterparts. They didn’t get adapted or refined. They simply disappeared. These ten cars showcase exactly that: features so unique, impractical, or era-specific that the industry quietly let them fade into history. 1958 Buick Limited Dagmar Bumpers Broad Arrow AuctionsThe 1958 Buick Limited was the last hurrah of the ultra-ornate ‘50s era before design sensibilities shifted. Among its many dramatic features, the one that turned the most heads, and likely bruised a few shins, were the prominent “Dagmar” bumpers. These large, bullet-shaped chrome protrusions sat at the front, giving the car a distinctive face that was both menacing and stylishly over-the-top.Named after the 1950s television personality Dagmar, these bumpers were an exaggerated flourish borrowed from jet-age styling and pin-up culture. While they offered no real performance benefit, they became a defining design cue of the era. As car safety and pedestrian standards evolved, the very idea of pointy front bumpers became untenable, sealing the Dagmars’ fate as an extinct relic. 1960 Chrysler Imperial Free-Standing Headlights The AutopianIn a time when most cars began tucking their lights into integrated fender lines, the 1960 Chrysler Imperial stood defiantly apart. Its free-standing headlights, housed in chrome pods completely separated from the body, gave it a bold, almost sci-fi look. They were inspired by Virgil Exner’s "Forward Look" design language, which pushed Chrysler styling into flamboyant new territory.The design made the Imperial instantly recognizable, but it came with compromises. The pods added weight, complexity, and exposed surfaces that were difficult to clean and maintain. And while the look was divisive even then, evolving design trends and stricter safety regulations ensured that no automaker would ever revisit the idea. 1957 Cadillac Eldorado Brougham Perfume Dispenser ThrottlextremeThe 1957 Cadillac Eldorado Brougham was Cadillac’s most expensive and ambitious offering to date, with a sticker price that shamed a Rolls-Royce. As you’d expect, it came loaded with features that bordered on absurd, including a factory-installed perfume dispenser. Nestled in the glove compartment, a vial of Arpège by Lanvin was part of a curated selection of luxury amenities.Cadillac saw the Brougham as a technological and luxury showcase, and the perfume dispenser added a touch of indulgence that even today feels over the top. Of course, time and practicality caught up. The feature had no measurable value, added to production costs, and didn’t age well with the car. Today, automakers still chase the luxury angle, but not quite with bottles of cologne built into dashboards. 1961 Lincoln Continental Suicide Doors Cooper Classic CarsThe 1961 Lincoln Continental made a big return with styling that embraced crisp lines and clean restraint. But its most iconic feature was its use of rear-hinged “suicide doors.” While the term might sound ominous, the design allowed easier ingress and egress, especially in chauffeur-driven scenarios. It also helped the Continental cut a regal silhouette that defined 1960s American luxury.These doors had long existed in early automotive history but fell out of favor due to safety concerns. A rear-hinged door could swing open into traffic or even during motion if not latched properly. Lincoln revived them for aesthetic appeal, but by the late ‘60s, they were phased out again. Despite their elegance, suicide doors have become an endangered design, reserved for ultra-limited editions or one-off show cars. 1973 Chevrolet Chevelle Laguna Body-Colored Urethane Nose Curbside ClassicWhen the 1973 Chevelle Laguna debuted, it brought a small but impactful innovation to the front end: a body-colored urethane nose instead of the traditional chrome grille and bumper. It was a response to new federal safety regulations requiring 5-mph impact protection, and GM took the opportunity to blend compliance with style.While the design helped give the Laguna a clean, modern front fascia, it also introduced durability issues. The urethane material didn’t age well and was prone to cracking, fading, or warping. Eventually, advances in bumper design allowed manufacturers to meet safety standards without sacrificing esthetics. The fully painted soft nose faded out quickly, surviving only a few model years before design priorities moved on. 1970 Plymouth Superbird Nose Cone And 19-Inch Wing Modern Car CollectorThe 1970 Plymouth Superbird remains one of the most recognizable cars to ever roll off a Detroit assembly line. Its distinctive aerodynamic nose cone and towering 19-inch rear wing weren’t just for show, they were engineered specifically to dominate NASCAR’s high-speed ovals. It was homologation at its most extreme, and it worked: the Superbird was a monster on the track.But for regular road use, the extreme aero features proved to be a liability. The nose cone made parking a nightmare, and the rear wing blocked rear visibility. Once NASCAR changed its rules to restrict such aero advantages, there was no need for such designs on street cars. The Superbird’s look was never replicated, and the winged warriors of that era disappeared just as quickly as they came. 1954 Mercedes-Benz 300 SL Tilt-Forward Steering Wheel Akrasia25 via Wikimedia CommonsThe 1954 Mercedes-Benz 300 SL Gullwing is best known for its iconic doors, but another unique feature helped drivers get behind the wheel: a tilt-forward steering column. Because the car’s high sills and fixed bucket seats made access difficult, Mercedes added a mechanism that allowed the steering wheel to swing forward for easier entry and exit.While ingenious for its time, the feature was specific to the SL’s body design and never really caught on elsewhere. Once tilt and telescoping wheels became standard, the forward-tilt design became unnecessary. Plus, modern cars favor simplicity and structural integrity over such mechanical quirks. Today, the 300 SL’s swing-away wheel is remembered as both a clever workaround and a charming quirk of a bygone era. 1975 Bricklin SV-1 Hydraulic Gullwing Doors With Safety Promises Classic Auto Show PlaceThe Bricklin SV-1 (short for “Safety Vehicle One”) was one of the most ambitious cars of the 1970s, created by Canadian entrepreneur Malcolm Bricklin. It featured hydraulic gullwing doors that were not only dramatic but tied into the car’s safety-first mission. The idea was that the doors wouldn’t swing out into traffic, and their hydraulics were designed to prevent accidental closure.In practice, though, the doors were notoriously finicky. The hydraulic system was underpowered, leading to slow or failed openings, especially in cold weather. While gullwing doors have reappeared in modern cars like the Mercedes SLS and Tesla Model X, the Bricklin’s system was an overcomplicated solution tied to a now-defunct safety vision. Its quirks make it unforgettable, but it’s a design that won’t be repeated. 1974 Volkswagen Thing Removable Doors And Windshield Bring A TrailerOriginally built for military use as the Type 181, the Volkswagen Thing was a boxy, quirky off-roader that fully embraced its utilitarian roots. One of its most unusual features was its removable doors and fold-flat windshield. You could literally strip the car down to its skeleton, making it feel more like a road-legal toy than a proper car.While fun, this level of modularity didn’t translate well to evolving safety standards. The open design lacked crash protection, and the removable elements made theft and weather exposure a constant concern. As SUVs became more refined and regulated, features like these had no place. The Thing remains a snapshot of an era where practicality sometimes took a backseat to charm. 1985 Saab 900 Center-Mounted Ignition Curbside ClassicSaab never followed convention, and nowhere was that more obvious than in the 1985 Saab 900 with its center-mounted ignition switch, placed between the front seats near the gear lever. Saab engineers argued it was a safer location in the event of a crash, and it added an anti-theft function by locking the transmission.This unique placement became a Saab trademark, but after the brand faded from the mainstream in the 2000s, the idea didn’t stick. Today’s cars favor push-button start systems and electronic key fobs that make ignition location almost irrelevant. But Saab’s design stood as a symbol of function-driven eccentricity that no other brand dared (and with good reason) to replicate.
