Who hasn’t dreamed of owning a sleek, powerful sports car? These magnificent machines embody speed, style, and an irresistible allure. But let’s be honest: while the fantasy is free, the reality of owning a brand-new, top-tier model often comes with a price tag that’s simply out of reach for most of us. That’s why so many performance addicts turn to the used market, hoping to snag one of these once-unobtainable beauties at a more reasonable price. It’s a thrilling quest, but it’s also packed with more risks than a high-stakes poker game.
Many car makers simply didn’t build these performance machines for durability or practicality. In fact, most are notoriously more expensive to maintain than your average, sensible ride. A seemingly sweet deal on a used sports car can quickly turn into a financial gamble, sometimes revealing unexpected mechanical issues that, frankly, were the factory’s fault. We’re talking about cars that, no matter how good the deal looks, could cost you more to keep running than to buy them, often before they even hit the 70,000-mile mark. If you want a truly pleasant driving experience without constant dread, there are definitely some models you need to approach with extreme caution. Here’s your friendly heads-up from your seasoned car-loving editor – let’s dive into the notorious list of used sports cars famous for causing big problems for unsuspecting owners.
1. **Mercedes-Benz SL 600**The Mercedes-Benz SL roadster, especially the R230 generation (2001-2011), truly embodies the German GT car ideal: stunning looks, matching performance, and a meticulously built feel. Among its engine options, the 5.5L V12 powering the SL 600 delivered ultimate performance with 500 horsepower, promising an exhilarating drive. It’s the kind of car that screams luxury and power, making it incredibly tempting on the used market.
However, that incredible V12, while potent, proved to be less reliable than other motors in the SL palette, excluding the AMG engines. V12 engines are notoriously expensive to maintain even when healthy, but when paired with the misplaced belief that a Mercedes-Benz is indestructible, you’re looking at a cascade of potential, costly problems. For a more worry-free experience, steer clear of the most powerful non-AMG engine. Instead, opt for a well-cared-for V8 model. They’re less expensive to obtain, maintain, and drive, largely because they are more common and less mechanically complicated, saving you money both initially and in the long run. Plus, the V12’s fuel mileage will also contribute to your headaches, often before it reaches the 70,000-mile mark.
2. **Lotus Esprit**Ever fantasized about channeling your inner James Bond? The Lotus Esprit, famously featured in “The Spy Who Loved Me,” offers a captivating alternative to the iconic Aston Martin DB5. On the used market, it’s considerably more affordable, with prices ranging from $30,000 to $100,000. It’s a truly striking, wedge-shaped design that screams classic supercar and pop-culture cred, promising a unique slice of automotive history without the colossal Aston Martin price tag.
But here’s the catch: while your wallet might initially thank you, the Esprit unfortunately falls quite short when it comes to long-term reliability, often developing costly maladies surprisingly early in its life. Its dramatic styling and unforgettable presence often mask a propensity for expensive mechanical issues. Despite its captivating visual appeal, you might find that the fantasy of owning one comes with a hefty price tag in the form of frequent garage visits and repair bills that quickly add up, easily diminishing the initial savings. A reliable, trouble-free ownership experience, especially before it hits significant mileage like 70,000, is often not part of the package.
3. **Lamborghini Gallardo (Gen. 1)**The rivalry between Ferrari and Lamborghini is legendary, but in recent years, Lamborghini has generally fared better in reliability. However, this positive trend wasn’t quite the case when the first-generation Gallardo debuted. This model was groundbreaking for Lamborghini, bringing supercar power to a wider audience. Today, it’s a stylish, impressive supercar that has become relatively affordable, often hovering around $70,000 for a used model, offering a slice of supercar history that still performs impressively.
Yet, despite its allure, that early Gallardo unfortunately comes bundled with plenty of mechanical issues, and fixing them is anything but cheap. From clutch wear that seems to happen overnight to temperamental electronics and various drivetrain problems, these issues can quickly erode any savings made on the purchase price. Your dream Lambo could end up spending more time with the mechanic than on the open road. Its capacity for expensive surprises certainly hasn’t depreciated, often rearing its head well before the 70,000-mile mark, turning an affordable entry into supercar ownership into a financial headache.
4. **Mazda RX-7 FD3S**Mazda has always stood out as an unconventional automaker, pioneering the rotary-engine technology in models like the RX-7 FD3S. These engines are incredible, producing an F1-like sound, revving beyond 10,000 rpm, generating impressive power for their size, and remaining remarkably lightweight. It’s an engineering marvel that delivers a driving experience truly unlike anything else, making the RX-7 a beloved icon for its striking design and unique performance.
However, if you’re chasing that unique, high-revving experience, be prepared for a distinctive set of maintenance headaches. This engine demands special attention: frequent apex-seal replacements are a common and costly reality, alongside meticulous oil level monitoring and more frequent oil changes than a conventional engine. Persistent electronic issues can also plague these complex systems. These problems tend to become more pronounced as the car racks up mileage, often starting to become problematic long before it reaches 70,000 miles. Owning an RX-7 is a labor of love that demands a deep understanding of its quirks and a healthy budget for specialized care.
5. **BMW E66 760Li**The early 2000s were a mixed bag for BMW. While they produced legendary models like the E46 M3, they also had notable missteps, with the E66 7-Series, particularly the V12-powered E66 760Li, being infamous. It was a bold attempt at luxury and technology but struggled to match the stellar reputation of its predecessor, the E38, largely due to its subpar build quality and controversial design. Even the top-of-the-line V12 variant shared the same design cues and, critically, the same reliability issues.
So, while a used E66 760Li with its powerful V12 and luxurious interior might seem like a steal today, be warned. The allure of a high-end BMW executive sedan at a bargain price often hides a multitude of sins beneath its stately exterior. These vehicles are known for developing complex electronic gremlins, expensive suspension problems, and a host of other mechanical issues that can quickly turn a sophisticated German luxury car into a frequent visitor to the service bay. These problems don’t always wait for high mileage either, often making their presence felt well before the car approaches the 70,000-mile threshold, making your “deal” a very costly commitment.
6. **2020 Mercedes-Benz S65 AMG**Here’s a truth bomb: just because something screams “luxury” doesn’t automatically mean impeccable quality or unwavering reliability. This has unfortunately proven true for many Mercedes-Benz models, both old and surprisingly new, like the opulent 2020 Mercedes-Benz S65 AMG. It’s designed to represent the pinnacle of German luxury and brutal performance, promising an unparalleled blend of comfort, speed, and sophistication. The glorious “AMG” badge suggests bulletproof reliability, but that assumption can be a dangerous deception.
The sophisticated complexity and immense power of the S65 AMG can ironically lead to a frustrating ownership experience, frequently involving unexpected and substantial repair costs. You could easily find yourself spending as much as its initial eye-watering MSRP on frequent trips to the mechanic just to keep this luxurious beast purring. The intricate V12 biturbo engine, advanced air suspension, and cutting-edge electronics are a marvel when they work, but a nightmare when they don’t. Even relatively young vehicles like a 2020 model are not immune to complex issues that crop up long before hitting significant mileage, making them risky propositions for used car buyers hoping for a smooth ride through the first 70,000 miles.

7. **TVR Sagaris**If “TVR Sagaris” doesn’t ring a bell, don’t worry – you’re not alone! Many Americans are unfamiliar with TVR because the eccentric British automaker never officially entered the U.S. market. But it’s a car worth knowing about, even if for cautionary tales. The Sagaris boasts one of the most striking, aggressive, and utterly wild exterior designs ever conceived, bristling with vents, sharp angles, and an unapologetic attitude that demands attention. For sheer presence, it’s in a league of its own, a raw and visceral visual spectacle.
However, for all its visual drama and performance ambition, the TVR Sagaris’s reliability unfortunately leaves an awful lot to be desired. This is precisely why you don’t see many Sagaris models, or indeed many TVRs, gracefully cruising on European roads. They are notorious for being temperamental, demanding, and prone to mechanical issues that can manifest surprisingly early in their lifespan. Owning a Sagaris is less about driving and more about a constant, passionate battle to keep it on the road, often involving costly fixes well before it even approaches the 70,000-mile mark. It’s a beautiful, terrifying, and financially demanding love affair that few are truly prepared for.

8. **2013 Ford Mustang Shelby GT500**When you hear “Shelby Mustang,” your mind probably conjures images of raw American power and legendary performance, right? And for good reason! But here’s a little secret: not all legends are created equal, especially when they’re rushed. After the passing of the iconic Carroll Shelby in 2012, Ford found itself in a bit of a pickle regarding the future of the Shelby brand. The 2013 model, while carrying that revered Shelby name, became the last release to have his approval, but it was reportedly ‘hastily put together’ by the automaker.
This means that unlike some of its meticulously engineered predecessors, the 2013 Shelby GT500 unfortunately ‘lacked the same level of refinement.’ What’s worse, it ‘inherited all the common issues found in the standard Mustang,’ which, let’s be real, are already a handful. But here’s the kicker: for a Shelby, those ‘repairs are significantly more expensive.’ So, if you’re eyeing this particular slice of American muscle, remember the golden rule: proceed with extreme caution. That “bargain” price tag could quickly balloon into a series of painful repair bills that will leave your wallet feeling mighty thin.
So there you have it: 8 sports cars and common high-mileage problems that, while incredibly tempting, might just be ticking time bombs for your wallet. Owning one of these beauties can be an absolute blast, but going into it blind is a recipe for regret. The thrill of a bargain can quickly fade when you’re staring down a repair bill that costs more than the car itself. Our goal here isn’t to burst your bubble, but to arm you with the knowledge to make smart decisions.
