How We Measure Reliability
Our reliability factor is a composite score based on:
- MOT failure rates per mile driven
- Component longevity — how far each part lasts before failure
- Repair frequency — how often things actually break
A score above 1.0 means the car fails less often than average. Below 0.85 means significantly higher repair risk.
Key Findings for 2026
Japanese brands dominate — Toyota, Honda, Suzuki, and Lexus take the majority of top spots. This isn't a stereotype; it's what the data shows across millions of MOT tests.
Budget doesn't mean unreliable — the Dacia Sandero and Suzuki Swift prove that cheap cars can be reliable. You don't need to spend premium money for premium reliability.
German premium comes at a cost — while well-engineered, BMW, Audi, and Mercedes models have more failure modes and higher repair costs when things go wrong.
What This Means For You
Reliability is just one factor in choosing a used car. A reliable car with expensive parts (Lexus IS) may cost more to own than a slightly less reliable car with cheap parts (Ford Fiesta).
