LONDON: The Toyota Aygo and Suzuki Swift are ranked as the most reliable used superminis or subcompacts in the United Kingdom (UK).
Leading UK used car warranty provider Warrantywise said the rankings were based on data from 2022-25.
With subcompacts continuing to dominate the UK’s used car market, Warrantywise has revealed which models are the most dependable in its latest "Reliability Index".
The supermini class is proving to be a haven for sensible buyers.
These small cars offer low running costs, accessible pricing, and, in many cases, impressive longevity.
It’s no surprise they remain the UK’s most popular type of used car, accounting for one in three (32.3 per cent) of all used cars sold in 2024.
Alongside the Aygo and Swift at the top, the Kia Picanto takes a strong third place with 86.8/100, followed closely by the Citroën C1 (82.8/100) and Peugeot 108 (80.3/100).
The Renault Clio also secures joint sixth place with the Ford KA, both scoring a respectable 79/100.
In eighth place is the Hyundai i10, scoring 78.4/100, followed by the Dacia Sandero in ninth (77.8/100), and in joint tenth position are the Hyundai i20 and MINI Cooper, both scoring 75.9/100.
"Our latest data backs up what many drivers already know – superminis are one of the safest bets you can make in the used car market," said Warrantywise managing director Antony Diggins.
"At a time when people are being more careful with their money, it’s reassuring to know that you don’t have to spend big to get a dependable car."
What’s especially impressive is how long many of these cars can go before they even need repair.
Over 60 per cent of the vehicles in the top 10 don’t show any faults until they’re at least eight years old.
Standouts included the Swift and the KA, averaging 8.7 years and nine year respectively before their first repair.
Warrantywise’s data showed that electrical issues account for over half of subcompact repairs, with engine faults making up just over 30 per cent.
