The most reliable used cars on UK roads, ranked by MOT first-time pass rate:
The Toyota Yaris consistently sits at or near the top. Its 1.0 and 1.3 litre engines are almost bulletproof, and the electrical systems rarely cause trouble. The Yaris is also cheap to fix when something does go wrong, because parts are readily available and labour is straightforward.
The Honda Jazz is another standout. It has one of the highest pass rates of any car tested, across all age brackets. Even at 10 or 12 years old, the Jazz maintains excellent reliability. Its "Magic Seats" system is famously durable, and the 1.3 i-VTEC engine is one of the most robust units Honda has ever produced.
The Mazda 3 rounds out the top three. Mazda's SkyActiv engines are relatively new in the grand scheme of things, but they are already showing impressive durability in MOT data. The 3 is a larger car than the Yaris or Jazz, making it a strong choice for drivers who need more space without sacrificing reliability.
