The Reliability Index figure calculates several factors: inconvenience caused, cost and rate of failure. It is based on data gathered from the vast number of claims which are made every year and shows motorists a good overview of cars currently on the road. The BMW 3 Series is in the top 20 of Britain's Reliability Index and this dealer currently has this second hand one in stock for just £43,500. That is a great value for this particular model and it's even better if there's less chance of shelling out for repair bills.
