The Reliability Index combines several elements - the price, inconvenience for motorists and rate of failure. It is made up of data gathered through millions of pounds worth of claims which are made each year and shows motorists a comprehensive guide of cars on the road. The BMW Z4 is among those ranked in the top 20 for reliability and this dealer currently has this second hand Sdrive M40i in stock for just £31,999. It's a fantastic deal for this particular model and even more so when you take into account that it's less likely to leave you with a bill for repairs.
