Warrantywise reveals most reliable superminis

Warrantywise has revealed which models are the most dependable in its latest Reliability Index.

The Toyota Aygo and Suzuki Swift are ranked as the most reliable used superminis, according to new data from the used car warranty provider, with each earning an impressive score of 88.6/100.

Warrantywise’s Reliability Index highlights the top 10 most reliable models, with rankings based on the frequency of faults, average age and mileage at the time of repair, and how long those repairs typically take to complete.

For consistency, Warrantywise has also categorised the superminis in line with Euro NCAP classifications – a widely recognised standard across Europe that helps ensure comparisons are made between like-for-like vehicles.

Alongside the Toyota Aygo and Suzuki 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 is the Hyundai i10, scoring 78.4/100, followed by the Dacia Sandero in ninth (77.8/100), and in joint tenth are the Hyundai i20 and Mini Cooper, both scoring 75.9/100.

Antony Diggins, managing director at Warrantywise, said: “With a number of these superminis not requiring major repairs until they’re nearly a decade old, and many models showing excellent cost-per-mile performance, they are an especially wise buy in today’s market.

“That said, no vehicle is perfect, and issues can happen, so we always encourage drivers to protect themselves with a comprehensive warranty – especially as labour and parts costs continue to rise.”

More than 60% of the vehicles in the top 10 do not show any faults until they are at least eight years old.

Standouts include the Suzuki Swift and the Ford KA, averaging 8.7 years and nine years, respectively, before their first repair.

Warrantywise’s data shows that electrical issues account for over half of supermini repairs, with engine faults making up just over 30%.

Repair costs can vary widely, with average bills ranging from £420 up to £1,118, and as high as £1,297 to £9,224, depending on the model and nature of the fault.
