Combining several points, the Reliability Index gathers the data based on millions of pounds worth of claims that are made each year. It considers: rate of failure, cost and the inconvenience for the driver and therefore gives motorists a comprehensive guide of the cars on the UK's roads today. The BMW 4 Series is in the top twenty of Britain's reliability index and this dealer currently has this used model in stock for just £16,995. That's already a really good deal for this particular model and it's even better if you are less likely to have to shell out for repairs.
