Cast your mind back to 2020. Porsche had just dropped the 718 Cayman GTS with that intoxicating 4.0‑litre flat‑six and a proper manual gearbox. Enthusiasts swooned. The muscular haunches, the tinted front lights, the giant wheels — it was a love letter to driving purity. Fast‑forward to 2026 and, well, the love is still there, but so is the price tag. Even a well‑kept used example demands a king’s ransom these days. But here’s the thing: the sports car universe has a galaxy of stars that deliver just as much — sometimes more — thrill, personality, and performance for the money. Some of them are exotic, some are electrified, and a few are downright bargains. So, if you’ve got your heart set on a Cayman GTS, take a breath and let’s go for a joyride through ten alternatives that should be on your radar in 2026.

1. 2020 Maserati GranTurismo — The Italian Opera on Wheels

We’ll kick things off with a car that made its big comeback in May 2020. The Maserati GranTurismo doesn’t shout; it sings. Its naturally aspirated V8 produces a soundtrack that even the finest turbochargers cannot mimic. ZF’s eight‑speed automatic — the same brainy gearbox you’ll find in Bentleys and Rolls‑Royces — swaps cogs so smoothly you’d swear the car is reading your mind. Even in 2026, the GranTurismo’s low‑slung silhouette and timeless trident grille turn more heads than most modern creations. It’s a grand tourer that can cosy up for a cross‑continent cruise and then, when the road gets twisty, remind you it’s still a fire‑breathing Italian. For the price of a used 718 GTS, you could slide into certified pre‑owned GranTurismo territory and own a slice of operatic drama. Chef’s kiss.

2. 2020 Toyota Supra — The Comeback Kid That Never Left

After a two‑decade hiatus, Toyota resurrected the Supra name, and boy, did it shake up the status quo. The fifth‑generation model arrived with a BMW‑sourced turbocharged inline‑six that punches out instant torque and a chassis that feels eager to play. In 2026, the Supra has aged like a fine whiskey — its styling still looks like it was sketched by a mischievous artist on a caffeine high. Better yet, the aftermarket community has embraced it with open arms, meaning you can tailor yours to a level of lunacy that no Cayman could ever match. A used 2020 Supra now sits in the sweet spot of affordability and tunability, making it the plucky underdog that can humble far pricier machinery. Seriously, this thing just keeps getting better with age.

3. 2020 Porsche 911 — The Eternal Benchmark

Wait, a Porsche to replace a Porsche? Bear with us. The 2020 Carrera models pack a 3.0‑litre twin‑turbo flat‑six that churns out 443 horses and 390 lb‑ft of tyre‑shredding torque. In 2026, the 992‑generation 911 has proven itself the definitive everyday supercar — it’s comfortable enough for the daily grind, yet ferocious enough to make your pupils dilate on a back road. That uni‑light LED taillight bar still looks futuristic, and the interior cocoons you in leather and aluminium like a bespoke cockpit. While the 718 Cayman GTS is a scalpel, the 911 is the surgeon’s entire tool kit. If you’re going to splurge on a Porsche, why not stretch for the icon?

4. 2020 Chevrolet Corvette Stingray — America’s Mid‑Engine Revelation

The C8 Stingray didn’t just raise the bar; it threw the bar into a new dimension. For a starting price of just under $60,000 (yes, back in 2020), you got a mid‑mounted 6.2‑litre V8 with 490 horsepower, exotic‑car proportions, and a removable targa top. Even now, in 2026, pre‑owned C8s hold their value remarkably well because they deliver an experience that was once reserved for six‑figure exotics. Step on the gas and the rear squats, the nose rises, and you’re launched forward with a guttural roar that makes the Cayman’s flat‑six sound polite by comparison. If the Porsche is the poised ballet dancer, the Corvette is the rock star that sets the stage on fire.

5. 2020 Polestar 1 — The Electric Grand Tourer Pioneer

Volvo’s performance arm dropped a bombshell with the Polestar 1, a carbon‑fibre‑bodied coupe that blends hushed electric running with a thundering gasoline heart. The combined output is around 619 horsepower, enough to make the $155,000 launch price feel almost justified. In 2026, this low‑production gem has become a coveted collector’s item — its futuristic Scandinavian design hasn’t dated a day. The silence in pure EV mode is almost eerie, but stomp the accelerator and it surges forward with the fury of a Norse god. It’s heavier than a dedicated sports car, true, but the serenity and storm duality is something the Cayman can’t even dream of.

6. 2020 Acura NSX — The Supercar That Learned to Listen

The second‑generation NSX arrived with a hybrid all‑wheel‑drive system and a twin‑turbo V6 that could out‑punch many V8s. Critics initially complained it lacked soul, but Acura quietly refined the suspension, steering, and software until the NSX became a bona fide weapon. By 2026, a used NSX represents an astonishing value for a supercar that can navigate city streets like a Civic and then transform into a track monster. The marque’s flagship feels like a precision instrument that eggs you on rather than intimidating you. And that subtle, under‑the‑radar styling? It ages more gracefully than most.

7. 2020 Mazda MX‑5 Miata — The People’s Champion

If spending close to six figures on a used Porsche gives you pause, the Miata is here to remind you that joy doesn’t need a price tag. The fourth‑generation ND has a humble 2.0‑litre four‑cylinder with 181 horses, yet it feels twice as quick thanks to a sub‑2,400 lb curb weight. The shifter snicks through the gears with a rifle‑bolt precision that embarrasses far costlier gearboxes. Even in 2026, you can pick up a pristine used Miata for less than the sales tax on some of the other cars here. It winks at you every time you toss it into a corner, and the entire car seems to giggle as you chase the redline. If you know, you know.

8. 2020 Lotus Elise — The Lightweight Legend

The Elise is proof that Colin Chapman’s “simplify, then add lightness” philosophy never goes out of fashion. Weighing just over 2,000 pounds, the 2020 model’s 220‑horsepower engine shouts from 0 to 60 in 4.2 seconds — numbers that still feel urgent in 2026. The steering talks to your palms in a language no power‑assisted system can replicate. Lotus even threw in a 7‑inch infotainment system with Apple CarPlay, so you can have your pure driving experience with a side of modern convenience. Pre‑owned examples with low miles are getting harder to find, but if you nab one, you’ve got a future classic that makes every commute an event.

9. 2020 Rimac C_Two — The Electric Hypercar That Rewrote Physics

We’re not even going to pretend this is a rational alternative, but if you have the means, why not chase a piece of automotive history? The Rimac C_Two delivers 1,914 horsepower and 1,696 lb‑ft of torque, rocketing to 60 mph in a physics‑defying 1.85 seconds. A two‑speed gearbox manages the torrent of electrons. In 2026, the C_Two (now the Nevera) remains one of the quickest production machines ever built, and early models are unicorns in the collector world. It makes the Porsche look like a horse and cart — and owner’s cheeks hurt for days from smiling. Sure, it costs seven figures, but the Cayman GTS might as well be a toyota in the face of this electric titan.

10. 2020 Alfa Romeo GTV — The Italian Passion Project

Alfa Romeo revived the GTV nameplate with a curvaceous second generation that channels the spirit of the original. A turbocharged 2.0‑litre four‑cylinder with 280 horsepower might not sound earth‑shattering, but the GTV’s charm lies in how it makes you feel — every drive becomes an occasion. The cabin wraps around you, the exhaust crackles on overrun, and the front end tucks into corners with an enthusiasm that borders on cheeky. Back in 2019‑2020, prices hovered between $40,000 and $75,000. Today, a well‑sorted GTV is a bargain ticket to la dolce vita, offering soul by the bucketload that a clinical Porsche just can’t replicate.

Whether you crave operatic V8s, electric vengeance, or featherweight agility, the market in 2026 is overflowing with machines that challenge — and often surpass — the 718 Cayman GTS in character and value. Porsche built a wonderful car, no doubt. But sometimes, the greener pastures are found by simply looking in a different direction. So go ahead, shake things up. Your dream drive is out there, and it might not have a crest on the hood.
