Most (and least) reliable sports cars

Sports cars, coupés and convertibles are often bought as toys to enjoy at the weekend. To help you pick a good one, we've rounded up the most and least dependable...

Most and least reliable sports cars

If you're lucky enough to be able to splash out on a sports car, coupé or convertible, you'll want it to put a smile on your face. And if you get a dependable one that needs little more than a service each year, it should do exactly that.

On the other hand, if it suffers costly faults and spends a lots of time in the garage, you might regret buying it.  So, to help you choose something reliable, we asked thousands of owners about their cars as part of our annual Reliability Survey.

Looking exclusively at the results for cars aged up to five years old, we've rated all the sports cars, coupés and convertibles we were told about.

The models with the fewest problems and those that cost the least to fix gained the top ratings, while those that languished in workshops for more than a week or racked up expensive repair bills are at the opposite end of the table.

The most reliable sports cars, coupés and convertibles

7. Mazda MX-5 (2015-present)

Mazda MX-5 2.0 Sport Nav+

The MX-5 is one of our favourite affordable sports cars and one of the most dependable. Owners told us 19% of their cars suffered a fault with the bodywork and non-engine electrics the main causes for concern. Even though many cars will be out of warranty, an impressive 58% were fixed for free, with no repair bills more than £500. Only 16% of cars were undriveable, and only 8% took longer than a week to fix.

Although 21% of TTs had a problem, the most common complaints were with the bodywork and non-engine electrics. Half of the cars we were told about were fixed for free and only 10% of owners paid out more than £1500 for repairs. Although the majority could still be driven, around half took more than a week to put right.
