Calculating several elements, the Reliability Index collates data sourced from a large number of claims that are made by motorists every year. It looks at: cost, inconvenience caused and rate of failure and gives you a detailed overview of the vehicles that are currently on the road. Fiat's 600 is in the top 20 of Britain's reliability index and this dealership currently has this second hand one for sale at just £18,998. That is a great value for this particular model and even more so taking into account that it's less likely to need extra trips to the mechanic.
