Best Used Convertibles Under $40,000 in 2027 (Ranked)
The used convertible market in 2027 is unusually deep, because automakers have quietly retired many drop-tops and demand for open-air driving never went away. That combination means a $40,000 budget now buys genuinely premium metal — low-mileage German roadsters, reliable Japanese hardtops, and even fast American muscle.
This ranking is built for buyers who want a second car or a daily that smiles, judged on reliability, real-world repair costs, ride and handling, weather sealing, and how well each car holds value. We weighted long-term ownership cost heavily, because a cheap convertible with an expensive roof mechanism is no bargain.
Every pick below is a real, road-tested choice you can find on dealer lots and private listings right now.
Direct Answer
The 2017-2019 Porsche 718 Boxster is our BEST OVERALL pick at roughly $38,000, delivering near-supercar handling and a robust folding top for sane money. For thrift, the 2016-2019 Mazda MX-5 Miata is our BEST VALUE at about $22,000, with the lowest running costs in the segment.
Buy on condition and service history first — a well-kept higher-mileage example beats a neglected low-mileage one every time.
How We Ranked
- Reliability — convertibles add roof motors, sensors, and seals, so we favored cars with proven mechanicals and few systemic failures.
- Ownership cost — fuel, insurance, tires, and parts availability matter as much as sticker price over a five-year hold.
- Driving enjoyment — steering feel, chassis balance, and top-down refinement are the whole point of buying a convertible.
- Top mechanism quality — power soft-tops and folding hardtops were judged on durability and the cost to fix when they fail.
- Resale and availability — we rewarded cars that are easy to find under budget and hold value, protecting your exit.
1. 2017-2019 Porsche 718 Boxster 🏆 BEST OVERALL
The 718 Boxster is the rare convertible that drives like a focused sports car with the roof up or down. The base car's 2.0-liter turbocharged flat-four makes 300 horsepower, and the optional PDK dual-clutch transmission delivers crisp, fast shifts. Mid-engine balance gives it steering precision that nothing else near this price matches, and the power soft-top folds in about nine seconds at speeds up to 30 mph.
Reliability is strong for a German sports car, though the turbo four can suffer bore scoring in neglected examples, so insist on documented oil changes and a pre-purchase inspection. Expect roughly $38,000 for a clean 2017 base model with reasonable miles; the flat-four's exhaust note is less charismatic than the old flat-six, but the chassis is sharper.
- Price: ~$38,000
- Pros: Sublime handling, durable top, strong resale, usable trunks front and rear.
- Cons: Pricey options inflate listings, firm ride, four-cylinder soundtrack divides buyers.
Verdict: The driver's choice and the most car for the money under $40,000.
2. 2016-2019 Mazda MX-5 Miata 💎 BEST VALUE
The fourth-generation MX-5 Miata (ND) is the cheapest convertible to own that you will never resent. Its 2.0-liter four makes 155-181 horsepower depending on year, but the car weighs barely 2,300 pounds, so it feels eager everywhere. The manual gearbox is among the best ever fitted to an affordable car, and the simple manual soft-top drops in seconds without leaving your seat.
Running costs are tiny: tires are cheap, fuel economy approaches 35 mpg highway, and the naturally aspirated engine is famously durable. Common issues are minor — occasional infotainment glitches and clutch wear on hard-driven cars. A clean 2017 Miata Club lands near $22,000, leaving budget for track days or maintenance.
- Price: ~$22,000
- Pros: Lowest running costs, brilliant handling, bulletproof drivetrain, fun at any speed.
- Cons: Tight cabin, modest power, road noise with the top up.
Verdict: The smart-money pick and the most joy per dollar in the segment.
3. 2015-2019 Ford Mustang GT Convertible
For buyers who want noise and muscle, the S550 Mustang GT convertible delivers a 5.0-liter V8 with 435-460 horsepower for well under budget. Independent rear suspension, added in this generation, makes it far more composed over rough roads than older pony cars. A clean 2017 GT convertible with the manual sits around $32,000.
The V8 is robust, but watch for clutch and oil-consumption complaints on hard-used cars, and budget for tires and fuel. The power soft-top is well sealed and quick. It is a heavy convertible, so it trades agility for straight-line thrust and a soundtrack that no four-cylinder can touch.
- Price: ~$32,000
- Pros: Huge V8 power, comfortable cruiser, strong parts and tuning support.
- Cons: Heavy, thirsty, cowl shake on rougher pavement.
Verdict: The American muscle choice for top-down highway runs.
4. 2017-2020 Audi A5 / A3 Cabriolet
The A5 Cabriolet is the grown-up convertible — a refined four-seat cruiser with Quattro all-wheel drive and a turbocharged 2.0-liter making around 252 horsepower. The acoustic soft-top is exceptionally quiet at speed, and the cabin quality embarrasses cars costing more. A well-kept 2018 A5 Cabriolet runs about $35,000.
Audi electronics and the convertible's hydraulics can be costly out of warranty, so favor cars with service records and consider a used-car warranty. All-wheel drive makes it a credible three-season car in snowy climates, a rarity among drop-tops. It is more boulevard cruiser than back-road weapon.
- Price: ~$35,000
- Pros: Quiet top, Quattro grip, premium interior, usable rear seats.
- Cons: Pricey repairs, numb steering, heavier than rivals.
Verdict: The all-weather luxury pick for buyers who want four seats.
5. 2017-2020 BMW 230i / 430i Convertible
BMW's small convertibles blend genuine driving feel with everyday usability. The 230i uses a 2.0-liter turbo with 248 horsepower and a slick eight-speed automatic, while the larger 430i adds room and a retractable hardtop on earlier cars. Rear-wheel drive and a balanced chassis make these the enthusiast's luxury convertible.
A clean 2018 230i is about $30,000.
These engines are strong but check for oil leaks, cooling-system parts, and the soft-top motor on the 2-Series. Maintenance done at independent specialists keeps costs sane. The 230i is the sweet spot — quick, tidy, and genuinely fun without the bulk of bigger BMWs.
- Price: ~$30,000
- Pros: Rear-drive balance, strong turbo torque, premium feel, compact size.
- Cons: Out-of-warranty repair bills, run-flat tire ride, options-dependent pricing.
Verdict: The driver-focused luxury convertible under budget.
6. 2016-2019 Chevrolet Camaro SS Convertible
The sixth-generation Camaro SS convertible is a serious performance bargain, packing a 6.2-liter LT1 V8 with 455 horsepower on the lighter, sharper Alpha platform. It outhandles its muscle-car reputation, with crisp steering and strong Brembo brakes. A clean 2017 SS convertible can be found near $36,000.
Visibility is poor and the cabin is snug, classic Camaro tradeoffs, but the powertrain is stout and the LT1 V8 is well understood by mechanics. The power top is quick and well sealed. For straight-line speed and cornering grip combined, little else under budget competes.
- Price: ~$36,000
- Pros: Massive V8 power, sharp chassis, strong brakes, great value.
- Cons: Cramped, poor outward visibility, firm ride.
Verdict: The performance-per-dollar muscle convertible.
7. 2016-2019 Fiat 124 Spider
Built on the Miata's platform but with its own Italian flavor, the Fiat 124 Spider swaps the Mazda four for a 1.4-liter turbo making 160-164 horsepower with more low-end torque. It rides slightly softer than the Miata and looks more grand-touring than sports car. Clean examples are a relative steal at around $20,000.
Because it shares Mazda underpinnings, reliability is generally good, though the MultiAir turbo engine wants strict oil changes and can show carbon buildup. Parts for the body and trim can be trickier than for the Miata. The Abarth trim adds a louder exhaust and stiffer tuning for spirited drivers.
- Price: ~$20,000
- Pros: Low price, torquey turbo, relaxed ride, Miata mechanicals.
- Cons: Pricier upkeep than Miata, slower parts supply, less crisp handling.
Verdict: The value alternative for buyers who want Italian style.
8. 2017-2020 Mercedes-Benz C300 Cabriolet
The C300 Cabriolet is the plush choice — a beautifully trimmed four-seater with a 2.0-liter turbo around 241 horsepower and an available AirCap wind-management system that keeps the cabin calm at speed. The multilayer soft-top is among the quietest in the class. Expect roughly $37,000 for a clean 2018 example with moderate miles.
Mercedes electronics and air-suspension components can be expensive, so a service history and inspection are essential. It is not a corner-carver, but as a refined open-air cruiser it is hard to beat. Optional all-wheel drive widens its appeal in cold climates.
- Price: ~$37,000
- Pros: Luxurious cabin, very quiet top, smooth ride, elegant styling.
- Cons: Costly repairs, soft handling, options inflate prices.
Verdict: The luxury cruiser for comfort-first buyers.
9. 2014-2018 Jeep Wrangler Unlimited
The Wrangler Unlimited is the unconventional convertible — its removable soft or hard top opens the cabin to the sky while delivering real off-road ability. The 3.6-liter Pentastar V6 makes 285 horsepower and is durable when maintained. Strong resale keeps prices firm, with clean JK four-door examples near $28,000.
It is the most practical pick here, seating five with genuine cargo space, but it rides like a truck and is noisy on the highway. Watch for the death wobble steering issue and rust on older units. Few vehicles match its blend of open-air freedom and go-anywhere capability.
- Price: ~$28,000
- Pros: Open-air and off-road, excellent resale, practical and rugged.
- Cons: Truck-like ride, road noise, steering and rust concerns.
Verdict: The adventure convertible for buyers who want utility.
10. 2015-2018 Volkswagen Beetle Convertible
The final Beetle Convertible is the easygoing, affordable cruiser that closes out the list. Its turbocharged 1.8-liter four makes about 170 horsepower, plenty for relaxed top-down driving, and the power soft-top operates quickly at low speeds. Clean examples are inexpensive, often around $19,000, the lowest entry price in this ranking.
It is not a sports car and the rear seat is tight, but the Beetle is comfortable, stylish, and cheap to insure. The 1.8 TSI engine is generally reliable; watch for water-pump and carbon-buildup issues common to VW turbos. As a friendly, low-stress convertible, it is an easy recommendation.
- Price: ~$19,000
- Pros: Lowest price, comfortable, distinctive style, easy to own.
- Cons: Modest performance, tight rear seat, VW turbo upkeep.
Verdict: The budget cruiser for relaxed open-air miles.
How to Choose
What to Look For
- Test the top fully: cycle the soft-top or hardtop several times and inspect seals for leaks, slow operation, or warning lights, since roof repairs are the costliest convertible-specific fault.
- Demand service records: turbocharged engines like the Porsche, BMW, and VW units reward documented oil changes and punish neglect with expensive failures.
- Check for water and rust: lift carpets and trunk liners to find dampness or corrosion that signals a leaking top or past flooding.
- Get a pre-purchase inspection: a $150 independent inspection routinely saves thousands on German and luxury convertibles bought used.
FAQ
What is the most reliable convertible under $40,000 in 2027? The Mazda MX-5 Miata is the most reliable, with a simple naturally aspirated engine, manual top, and cheap parts. The Jeep Wrangler and Ford Mustang GT are also durable when maintained, while German luxury models demand careful upkeep.
Are used convertibles expensive to maintain? It depends on the brand. A Miata or Fiat 124 costs little to run, while Porsche, Audi, and Mercedes convertibles carry premium repair bills. The roof mechanism itself is the main added expense versus a fixed-roof car, so test it thoroughly before buying.
Soft top or folding hardtop — which is better used? Soft tops are lighter, cheaper to repair, and dominate this list. Folding hardtops, found on some earlier BMW and Mercedes models, offer better security and quiet but have more motors and panels that can fail and cost more to fix.
Which convertible holds its value best? The Porsche 718 Boxster and Jeep Wrangler hold value best. The Boxster's enthusiast demand and the Wrangler's broad appeal keep resale strong, protecting your investment if you sell within a few years.
