The Reliability Index figure combines - the amount the car fails, cost and the inconvenience for the driver. It's based on data gathered through the vast number of claims which are filed by drivers each year and therefore shows motorists a detailed overview of the reliability of cars on the road today. BMW's 1 Series is in the top 20 of Britain's Reliability Index and this dealer currently has this second hand model in stock for just £42,500. It's already a bargain for this particular model, even more so taking into account that it's less likely to let you down and cost you extra money in repairs.
