The Reliability Index figure analyses several elements - the inconvenience for motorists, rate of failure and cost. It's made up of data collected from the large number of claims that drivers make every year and provides you with a comprehensive guide of the reliability of cars on the road today. BMW's X3 is in the top twenty of the UK's Reliability Index and this dealership in Milton Keynes currently has this second hand model in stock for only £53,995. It's a great value for this model, even more so if you take into account that it's less likely to leave you with a repair bill.
