The most reliable used convertible to buy in 2025

The Mazda MX-5 Miata (ND generation, model years 2016–2023) is the most reliable used convertible for most buyers, combining top-tier dependability with low running costs and a simple, durable soft top. For those who want a four-seat hardtop convertible with a similarly strong track record, the Lexus IS 250C/350C (2010–2015) is the standout alternative. This article explains why these models rise to the top, which years to target, what to inspect on any used convertible, and how they compare with other trustworthy options.

Why the Mazda MX-5 Miata tops the list

Across multiple reliability sources and owner surveys, the MX-5 Miata has built a reputation for mechanical simplicity and longevity. The ND generation’s naturally aspirated 2.0-liter engine and Aisin automatic/manual transmissions are proven, while the straightforward soft-top mechanism limits the roof-related problems that often affect convertibles. Insurance, tires, brakes, and fuel costs are typically lower than rivals, and parts availability is excellent.

The following points outline the MX-5 Miata’s key reliability advantages that make it a safe used buy for most shoppers.

• Consistent reliability reputation: Frequently rated above average by consumer surveys; Mazda brands score well in recent dependability studies.
• Simple, robust powertrain: The 2.0L Skyactiv-G engine and six-speed transmissions have strong durability records when maintained.
• Durable soft top: The manual cloth roof is quick, light, and less failure-prone than complex power folding systems.
• Low running costs: Excellent fuel economy, modest tire sizes, and widely available parts keep ownership expenses down.
• Strong resale and community support: A large owner base and aftermarket makes upkeep easier and cheaper.

Taken together, these traits mean fewer surprise repairs, predictable maintenance, and more time enjoying the car with the top down.

Best years and trims to target (ND Miata)

While all ND Miatas are solid, some model years offer desirable updates. Here’s how to prioritize them based on performance, features, and value.

1. 2019–2023 (ND2, 181 hp): Revised engine with more power and a broader powerband; many cars include modern driver aids and smartphone integration.
2. 2016–2018 (ND1, 155 hp): Lightest variants with the purest feel and strong reliability; often the best value on a budget.
3. RF models (2017–2023): Power targa-style hardtop adds year-round usability with minimal reliability trade-offs; just verify roof operation and seals.

All ND years remain dependable choices. Prioritize service history, careful ownership, and a clean inspection over chasing a specific trim.

Other exceptionally reliable convertibles worth considering

If the Miata doesn’t fit your needs—more seats, a hardtop, or greater highway refinement—these alternatives are standouts for reliability while still offering open-air fun.

• Lexus IS 250C/350C (2010–2015): Bulletproof Lexus engineering with a folding hardtop and four seats; prioritize maintenance of roof seals and drains.
• Toyota Camry Solara Convertible (2004–2008): Older but durable, with inexpensive parts and easy servicing; a relaxed cruiser that’s cheap to own.
• Honda S2000 (2004–2009): Legendary reliability and performance; values are high and condition matters, but mechanicals are robust.
• Mercedes-Benz SLK/SLC (R172, 2012–2020): Generally solid with a hardtop; ensure roof hydraulics and electronics are healthy.
• Porsche Boxster 987.2 (2009–2012) and 981 (2013–2016): Stronger reliability than earlier 986/987.1; maintenance costs are higher but issues are fewer when serviced.
• BMW 230i Convertible (F23, 2017–2021): The B46/B48 four-cylinder is more dependable than older N20 engines; inspect top mechanism and cooling system.

Each of these models can deliver reliable ownership when bought carefully; focus on service records and a clean pre-purchase inspection to minimize risk.

What to inspect on any used convertible

Convertibles add unique wear points beyond standard mechanical checks. A thorough inspection helps you avoid hidden costs related to the roof, water management, and body rigidity.

• Roof operation and condition: Cycle the top multiple times; look for hesitations, noises, misalignment, frayed fabric, or cracked plastic windows.
• Seals and water ingress: Check weatherstrips, drains, and carpets for dampness or mold; inspect trunk and rear seat wells for leaks.
• Body/chassis: Listen for rattles over bumps; examine for accident repairs, subframe corrosion, and alignment issues.
• Electrical systems: Test window drops/raises (frameless doors), roof sensors, trunk interlock, and infotainment; water can cause intermittent faults.
• Service history: Confirm regular fluid changes (engine, transmission, differential), documented roof maintenance, and recall completion.
• Tires and brakes: Mismatched or budget tires and worn brakes can indicate neglect; convertibles benefit from quality rubber for rigidity and grip.

A pre-purchase inspection by a marque-knowledgeable technician, ideally including a leak test, is the best insurance against costly surprises.

Running costs and ownership experience

The Miata leads not just in reliability but also in affordable ownership. Routine maintenance is simple, and consumables are inexpensive compared with premium-brand rivals. Insurance is typically reasonable for a two-seat roadster, and the soft top is economical to repair or replace if needed. By contrast, hardtop convertibles and premium European models often incur higher costs for roof hydraulics, electronics, specialty tires, and scheduled services.

Market pricing snapshot (U.S., late 2025)

Prices vary by mileage, condition, location, and season. These ranges reflect typical asking prices for well-kept, clean-title cars.

• Mazda MX-5 Miata ND (2016–2018): roughly $16,000–$24,000; ND2 premium for 2019–2020 at about $22,000–$30,000.
• Mazda MX-5 Miata ND (2021–2023): roughly $25,000–$34,000; RF models can add $1,500–$4,000 depending on spec.
• Lexus IS 250C/350C (2010–2015): roughly $13,000–$25,000, with condition and mileage driving variance.
• Honda S2000 (2004–2009): commonly $25,000–$45,000+ for low-mile AP2 cars; prioritize provenance.
• Porsche Boxster 987.2/981 (2009–2016): roughly $24,000–$50,000+, with maintenance history crucial to value.

As always, buy the best-documented example you can afford; a cheaper car with deferred maintenance is rarely a bargain after repairs.

Bottom line

For most shoppers, the Mazda MX-5 Miata (2016–2023) is the most reliably satisfying used convertible you can buy, balancing mechanical durability, low costs, and everyday usability. If you need four seats and a hardtop, the Lexus IS 250C/350C is the safest alternative. No matter which model you choose, a careful inspection of the roof system, seals, and service history will make the difference between a carefree cruiser and an expensive project.

Summary

The most reliable used convertible for most buyers is the Mazda MX-5 Miata (ND, 2016–2023), with the Lexus IS 250C/350C (2010–2015) as the top four-seat hardtop option. The Miata’s simple, proven powertrain and durable soft top keep repairs and running costs low. Consider other solid choices like the Toyota Solara Convertible, Honda S2000, Mercedes SLK/SLC, Porsche Boxster (987.2/981), and BMW 230i Convertible if they better fit your needs, but prioritize condition, roof health, and documented maintenance above all.
