Most (and least) reliable older small cars

More small hatchbacks are sold than any other type of car, so there are plenty of used examples to choose from. But which are the most and least dependable?...

Most and least reliable older small cars

Small cars are usually cheap to buy, but if you pick an unreliable model it could land you with sky-high repair bills. The good news is that these cars aren't laden with high-tech gadgetry, so there's less to go wrong than there is on a luxury barge, but there's still a big difference in the durability of the best and worst.

With data from nearly 13,000 car owners across the UK, that's where the What Car? Reliability Survey can help you sort the good from the bad. 

Here, we're looking exclusively at the results for used small cars aged between six and 20 years old. We've rated each one according to the seriousness of the faults it's suffered and the cost of fixing it.

2015 Kia Picanto 1 Air review - DO NOT PUBLISH

What Car? reliability rating 98.5%

The Picanto may not be as agile or refined as the VW Group’s triumvirate of the Seat Mii, Skoda Citigo and Volkswagen Up, but it trounces them for dependability. Only 6% of cars went wrong and the only area affected was the battery. All cars were fixed in a day or less and no bills exceeded £100. 

Owner comment: “The thing I like most about my car is how reliable it has been. It comes with a seven-year warranty, but I’ve not needed to use it.”
