Accounting for several elements, the Reliability Index collates data sourced from the millions of pounds worth of claims which are filed by drivers throughout each year. It looks at: rate of failure, the inconvenience for drivers and price, providing you with a comprehensive guide of the cars on the road. BMW's 4 Series is in the top twenty of the United Kingdom's reliability index and you can pick up this second hand one from this dealer for just £10,499. That is already a bargain for this model and even more so when you take into account that it's less likely to leave you with a repair bill.
