Back in the mid-2010s, a handful of sedans were rewriting the rulebook. They packed monstrous horsepower, carved corners like sports cars, and could humble supercars in a straight line—all while ferrying the family in leather-lined comfort. Today, in 2026, the depreciation hammer has done its work, turning these once six-figure autobahn assassins into some of the most jaw-dropping performance bargains on the used market. With average prices hovering around the $30,000 mark, many can now be snapped up for less than a new economy hatchback. It’s a buyer’s market for anyone with a taste for speed and a willingness to stomach the occasional eye-watering repair bill. Here are ten speed titans from around 2015 that have aged into attainability—some so cheap they’d make a sensible accountant raise an eyebrow.

2017 Audi S8 Plus – The Autobahn Limo That Humiliates Supercars

The D4 Audi S8 Plus was a velvet sledgehammer. Its twin-turbo 4.0-liter V8 sent over 600 hp to all four wheels via Quattro all-wheel drive, enabling this 4,400-pound luxury liner to rip through the quarter mile in a tick over 12 seconds at nearly 115 mph. Edmunds praised its ability to handle like a smaller sedan, with crisp steering and a well-sorted suspension. The standard 155-mph limiter was merely a suggestion; with the dynamic package, it could storm all the way to 190 mph. Original MSRPs nudged six figures, yet today clean examples change hands in the low $30,000 range, with higher-mileage units dipping below $20,000. It’s a phenomenal amount of car for the money—a true wolf in banker’s clothing—provided you’re ready for the maintenance bills that come with a flagship German luxury sedan.

BMW M5 (F10) – The Physics-Defying Powerhouse

In 2015, the F10 M5 was a four-door that seemed to bend the rules of physics. Its twin-turbo 4.4-liter V8, in Competition guise, pumped out 560 hp and a relentless wave of torque. Motoring journalists hyperbolized it as “a four-door that rewrites the laws of physics.” Like the Audi S8, the M5’s forced-induction V8 replaced a naturally aspirated V10, robbing it of some aural drama but bestowing absurd midrange punch. Depreciation hit hard: early examples now live under the $25,000 mark—a fraction of the original $90,000+ window sticker. Of course, maintenance can be a wallet-drainer, with over-engineered German complexity lurking beneath every panel. Pristine, low-mileage Competition models still command north of $40,000, but even those are a steal compared to a new M3.

Cadillac CTS-V (Second Gen) – America’s Supercharged Sledgehammer

If 6.2 liters of American V8 isn’t enough, bolt on a supercharger. The second-gen CTS-V borrowed its 6.2-liter LSA engine straight from the Corvette ZR1, detuned to a still-insane 556 hp. In 2015, it was one of the fastest sedans to wear a bowtie, capable of dispatching the quarter mile in 12 seconds flat and hitting a claimed 191 mph top end. Today, the sedan is a bona fide bargain in the low $30,000s, but the real unicorn is the CTS-V Wagon—some mint examples have skyrocketed past $110,000, proving that manual, long-roof madness never goes out of style.

Chrysler 300 SRT8 – The Big-Bore Muscle Sedan

Chrysler stuffed a 470-hp 6.4-liter HEMI V8 into the already imposing 300, creating a muscle sedan that could run door-to-door with M and AMG hardware on the drag strip. Without forced induction, launch was a touch lazier, but mid-12-second quarter-mile passes were the norm in 2012 testing. Now in the belly of its depreciation curve, these big-bore brutes trade hands for just over $20,000—making them one of the cheapest ways to park nearly 500 hp in your driveway. The interior might feel dated, but the soundtrack from that HEMI makes up for it with every cold start.

Jaguar XFR (X250) – The British Bruiser with a Howling Heart

Ending production around a decade ago, the XFR was a swan song for Jaguar’s supercharged V8 heritage. A 500+ hp 5.0-liter unit delivered a snarling exhaust note and oodles of English character, making the XFR a compelling left-field rival to the M5. Independent tests saw 0–60 mph in under 4.5 seconds and a top end well beyond 150 mph when the governor was removed. The even spicier XFR-S pushed the envelope to 186 mph. Today, higher-mileage XFRs often sell below $20,000, while pristine examples and XFR-S models hover in the $40,000 range. It’s a charming, last-of-the-line V8 Jag that won’t break the bank—just maybe your self-control at every tunnel.

Mercedes-AMG E63 (W212 Pre-Facelift) – The 6.2-Liter Soundtrack on Wheels

The pre-facelift W212 E63 packed a hand-built 6.2-liter naturally aspirated V8 that delivered spine-tingling performance and a goosebump-inducing exhaust note. It could dispatch the quarter mile in just over 12 seconds and charge to 186 mph without breaking a sweat. Depreciation has made these icons accessible under $25,000, though the AMG-sized maintenance bills remain faithfully sky-high. The facelifted W212 may have traded that legendary 6.2 for a twin-turbo 5.5, but they’re depreciating just as beautifully and are worth a long look for those who prefer their violence with forced induction.

Audi RS7 (C7) – The Five-Door Supercar Humiliator

The RS7’s twin-turbo 4.0-liter V8 cranked out over 550 hp, letting this sleek fastback-shaped sedan embarrass supercars in rolling races. In 2015, Motor Trend launched one to 60 mph in a scant 3.4 seconds. Electronically capped at 155 mph, an optional dynamic package raised that to 174 mph, and unrestricted examples reportedly kissed 190 mph. Original stickers brushed $110,000, but early models now dip into the $30,000 range—an outrageous bargain for this level of speed wrapped in avant-garde styling. It’s a practical rocket that still turns heads at the country club.

BMW 760Li (F02) – The V12 Royal Barge with a Pulse

One of only two deviations from the V8 dogma here, the stately 760Li wielded a silken twin-turbocharged V12 churning out 535 hp. It wasn’t built for dragstrip heroics; instead, power delivery was turbine-smooth, making it a chauffeur’s car that could sprint from 60 to 120 mph like a private jet taking off. Many examples racked up interstellar mileage ferrying executives, which is perfect for today’s buyer: $20,000–$25,000 buys you a rolling testament to excess that, with its limiter removed, could transcend 190 mph on the Autobahn. Just bear in mind that a V12’s thirst is matched only by its appetite for expensive fluids.

Maserati Quattroporte GTS – Ferrari-Powered Italian Style

The Quattroporte GTS served up a Ferrari-built twin-turbo 3.8-liter V8, sumptuous Italian leather, and a top speed brushing 200 mph. It was effortless rapidity, delivered with operatic flair and a chassis that leaned more toward grand touring than razor-sharp handling. Italian depreciation is famously brutal, and the GTS is no exception: early examples now slip under $20,000, with realistic average prices hovering around $23,000 according to market data. That’s a lot of modern Ferrari-derived soul for less than a well-optioned Toyota Camry. Just budget for the inevitable quirks—it’s part of the charm.

Volvo S60 Polestar – The Quirky Scandinavian Sleeper

Sweden’s answer to the super-sedan arms race was the limited-run S60 Polestar. Its turbocharged 3.0-liter inline-six sent power through all four wheels, wrapped in a discreetly handsome body that fooled no one when the boost hit. It was never the fastest of the group, but its oddball charm and Scandinavian cool made it a cult favorite. Rarity has kept values buoyant, but clean examples still land around $30,000, with Kelley Blue Book fair purchase numbers dipping as low as $16,271. It’s the quirkiest entry here—a true sleeper that rewards those who appreciate a different kind of performance statement.

In an era of rising new-car prices, these depreciation all-stars prove that patience pays off. With a healthy dose of mechanical sympathy and a trusty independent mechanic, you can own a piece of automotive excess that once graced magazine covers and YouTube glory runs—all for the price of a sensible commuter. Just be sure to budget for tires, because these super sedans will eat them for breakfast.
