The UK Reliability Index figure analyses several elements - rate of failure, inconvenience for drivers and cost, it comes from data that has been collected through the large number of insurance claims which are made by motorists throughout each year and provides motorists with a good overview of the cars on the road today. BMW's M4 is in the top twenty of Britain's Reliability Index and this dealer currently has this second hand model for sale at just £93,295. That's a bargain price for this particular model and even more so taking into account that it's less likely to leave you with a bill for repairs.
