Best and worst coupes and convertibles for reliability

Most reliable coupes and convertibles

Coupes and convertibles are some of the most exciting cars to own. They're swift, sporty and should be fun to drive day to day. They also need to be dependable - and that's where our our 2017 Reliability Survey can help.

We asked more than 14,200 people to tell us about any faults their cars had suffered during the past 12 months. We asked how long the problem kept the car off the road and how much they'd had to pay to get it fixed.

Those that had the least problems and were cheapest to fix gained the top ratings, and those that languished in workshops for days on end and racked up expensive repair bills were given the lowest ratings.

Here's our round-up of the best and worst performers in the small SUV league.
