Combining several factors, the Reliability Index collates data sourced from millions of pounds worth of insurance claims that people make throughout each year. It considers: price, rate of failure and inconvenience and gives motorists a detailed overview of cars on the UK's roads. The BMW M5 is among those ranked in the top 20 for reliability and this dealership currently has this used one in stock for only £96,500. That's already a fantastic deal for this model, even more so when you take into account that it's less likely to leave you with a repair bill.
