Calculating several factors, the Reliability Index gathers data sourced from a large number of insurance claims which are made throughout each year. Looking at cost, a car's failure rate and inconvenience, it provides motorists with a good overview of cars on the road today. BMW's 4 Series is in the top twenty of the United Kingdom's reliability index and this dealer has this second hand model in stock for just £17,498. It's a really great price for this particular model and even better if you're less likely to be forking out for repairs.
