The Reliability Index figure takes several points into account - the rate of failure, inconvenience for the driver and cost. It's based on data gathered from a vast quantity of insurance claims which are filed every year and provides motorists with a good overview of cars that are on the UK's roads. The BMW 6 Series is in the top 20 of the UK's Reliability Index and this dealer currently has this second hand model in stock for only £13,995. That is already a great value for this model, particularly if you take into account that it's less likely to leave you with a bill for repairs.
