This is a short list, not an exhaustive ranking: three sports cars on sale for 2026, each backed by a model-specific result — the best repair record of the three (Miata), a three-year dependability award (Corvette) and the top initial-quality score of any vehicle (911). Other sports cars also have published results.
The three cars are listed by starting price, lowest first, and each section shows the weak spots in the data alongside the strengths.
How We Judged Reliability
We used three published measures:
- J.D. Power Vehicle Dependability Study (VDS): problems reported by original owners after three years of ownership. The 2025 study surveyed 34,175 owners of 2022 models.
- J.D. Power Initial Quality Study (IQS): problems reported in the first 90 days of ownership. The 2026 study surveyed 78,514 buyers and lessees of 2026 models.
- RepairPal reliability ratings: a rating out of 5, an estimated annual cost of unscheduled repairs, and the probability that a repair is severe. RepairPal compares each car with its own category, so a Porsche is scored against other luxury cars.
Both J.D. Power studies count problems per 100 vehicles (PP100), where lower is better. Initial quality is not the same as long-term durability, so each result below names the study it comes from.

The Three Cars Side by Side
| Model | 2026 status and starting MSRP | Horsepower (manufacturer) | J.D. Power evidence | RepairPal rating and est. annual repair cost | Chance a repair is severe (RepairPal) |
|---|---|---|---|---|---|
| Mazda MX-5 Miata | 2026 model on sale. Sport from $30,730 (mazdausa.com) | 181 hp | No model-level award named in the 2025 VDS or 2026 IQS releases. Mazda brand: 161 PP100 in the 2025 VDS | 4.0/5, 8th of 21 subcompact cars. About $429 a year | 10% (subcompact average 11%) |
| Chevrolet Corvette | 2026 Stingray on sale. From $70,000 (chevrolet.com) | Up to 495 hp (max. available, Stingray) | 2025 VDS: model-level award (2022 models after three years) | 3.0/5, 23rd of 24 midsize cars. About $737 a year | 22% (midsize average 12%) |
| Porsche 911 | Current model; 2026 models were surveyed in the 2026 IQS. 2026 pricing no longer listed; 2027 Carrera from $135,500 (porsche.com/usa) | 388 hp (2027 Carrera) | 2026 IQS: highest-ranking model overall, 110 PP100. 2025 IQS: highest-ranking model overall, 116 PP100 | 2.0/5, 25th of 31 luxury midsize cars. About $1,072 a year | 22% (luxury midsize average 12%) |
Starting prices are as listed on each manufacturer's U.S. website on September 30, 2026. They exclude taxes, title and registration; check each manufacturer's disclosures for destination charges. RepairPal figures cover the model line, not the 2026 car specifically.
Mazda MX-5 Miata
The Miata has the strongest repair record of the three. RepairPal gives it 4.0 out of 5, 8th of 21 subcompact cars. Owners spend an estimated $429 a year on unscheduled repairs, against $456 for subcompact cars and $652 across all vehicles. They visit a shop about 0.3 times a year, and 10% of repairs are severe, slightly better than the 11% subcompact average.
What's missing is a model-level J.D. Power result: neither the 2025 Vehicle Dependability Study nor the 2026 Initial Quality Study names the Miata among its award winners. At the brand level, Mazda scored 161 PP100 in the 2025 VDS, second among mass-market brands.
The 2026 MX-5 Miata Sport starts at $30,730, and the retractable-hardtop RF starts at $38,750. It uses a 2.0-liter four-cylinder engine rated at 181 hp.
- Starting MSRP: $30,730 (2026 Sport); RF from $38,750
- RepairPal: 4.0/5, about $429 a year, 10% of repairs severe
- Best for: drivers who want the lowest running costs and the most consistent repair data on this list
Chevrolet Corvette
The Corvette is the only car on this list with a recent J.D. Power award for long-term dependability. It received a model-level award in the 2025 Vehicle Dependability Study, which surveyed original owners of 2022 models after three years. Corvette Blogger reported it as first place in the Premium Sporty Car category. The 2026 study, which covered 2023 models, did not name the Corvette among its award winners.
RepairPal's data adds a caveat. It rates the Corvette 3.0 out of 5, 23rd of 24 midsize cars. Owners visit a shop about 0.3 times a year, in line with the midsize average, but repairs cost more: about $737 a year against a $526 category average, and 22% of repairs are severe, against 12% for midsize cars. In short, problems are infrequent, but they can be expensive when they happen.
The 2026 Corvette Stingray starts at $70,000, with up to 495 hp available and an 8-speed dual-clutch transmission.
- Starting MSRP: $70,000 (2026 Stingray)
- J.D. Power: model-level award, 2025 Vehicle Dependability Study
- RepairPal: 3.0/5, about $737 a year, 22% of repairs severe
- Best for: buyers who want V8 performance backed by a three-year dependability award, and who will budget for the occasional costly repair
Porsche 911
The 911 has topped J.D. Power's Initial Quality Study two years running. It was the highest-ranking model overall in the 2026 Initial Quality Study, at 110 PP100, and in the 2025 study, at 116 PP100. Porsche was the highest-ranking brand overall in the 2026 study, at 138 PP100, and the Stuttgart plant that builds the 911 shared J.D. Power's 2026 Gold Plant Quality Award for Europe and Africa.
Initial quality covers only the first 90 days, though, and the long-term repair data is less flattering. RepairPal rates the 911 2.0 out of 5, 25th of 31 luxury midsize cars. Owners visit a shop less often than the category average, about 0.5 times a year against 0.6, but repairs are costly: about $1,072 a year against a $739 category average, and 22% of repairs are severe, against 12%.
Porsche's U.S. site now lists the 2027 911, with the Carrera starting at $135,500.
- Starting MSRP: $135,500 (2027 911 Carrera, the model year now listed)
- J.D. Power: highest-ranking model overall, 2025 and 2026 Initial Quality Studies
- RepairPal: 2.0/5, about $1,072 a year, 22% of repairs severe
- Best for: buyers who put build quality first and can absorb the highest repair costs on this list
What About the Porsche 718 Boxster and Cayman?
The gasoline 718 Boxster and Cayman are not on this list because there is no 2026 model. In 2024, Porsche's head of production said gasoline 718 production would end in mid-2025 for markets outside Europe, making 2025 the final model year. Porsche's U.S. site lists only 2025 718 models, and by February 2026 its U.S. configurator no longer accepted 718 builds. What's left is remaining 2025 inventory and used cars.
If you're shopping for one, the repair data is worth knowing. RepairPal rates the Boxster 2.5 out of 5 (15th of 17 luxury compact cars, about $952 a year, 17% of repairs severe) and the Cayman 2.0 out of 5 (16th of 17, about $1,135 a year, 19% severe). Neither the 2025 VDS nor the 2026 IQS release names a 718 model among its award winners. On a used example, a documented service history and an independent pre-purchase inspection matter more than usual.
Which One Fits Your Situation
- Lowest running costs and the strongest repair data: Mazda MX-5 Miata
- Long-term dependability award with V8 performance: Chevrolet Corvette
- Best initial build quality, with the highest repair costs: Porsche 911
