1. Ford C-Max (2011-2019)

Reliability rating 100%

What went wrong? Nothing

The C-Max has been around for a long time, and it's ageing well; none of the cars we were told about suffered any faults at all. If you're looking for a dependable and practical motor can look past the swathes of SUVs on offer, the C-Max is worth putting on your shortlist.

Owners of the five-seat Active Tourer and seven-seat Grand Tourer had trouble with their cars in 24% of cases, with the most commonly cited areas being engine electrics and the gearbox/clutch. Happily, all cars remained driveable and two-thirds were fixed in a day or less. While 87% of work was done under warranty, a small percentage of owners had to pay bills totalling up to £500.
