The UK Reliability Index figure combines several elements - rate of failure, price and inconvenience caused. It's based on data sourced from the vast number of insurance claims that are filed each year and therefore gives motorists a good overview of cars on the road today. BMW's X4 M is in the top twenty of Britain's Reliability Index and at this dealer you can buy this second hand one for just £41,990. That's a really good deal for this particular model and it's even better if you take into account that it is less likely to leave you with a repair bill.
