In these pages we focus on design, breakthroughs, enabling technologies and concepts and it’s rare that we look at product that has been in the marketplace for some time, much less second-hand product. But when we saw what a UK automotive warranty company was up to, we know you'll agree that it’s worth a mention. As a privately owned insurance intermediary, the firm collects lots of data about warranty issues – something you’ll never find out from the only other people who have access to the information (the manufacturers). In a very clever move, it has taken this secondary data and produced a reliability index – an independent comparison of frequency of failure across the 55,000 vehicles it insures. Read on for a list of the 100 most reliable used cars over the past decade. And before you take a peek, have a guess at where the best Japanese, German, Swedish, British, Korean and French-built cars will rank. You won’t even come close!
