The Index is formed by Manufacturer and also by type/model. This ensures that no individual poorly or highly performing model can unduly influence a manufacturer’s overall Index figure.
Manufacturer Ratings
All that particular manufacturer’s ratings added up into one figure that should expose whether cars from this stable are generally reliable – or maybe not! Perhaps most models lack in a certain area, Audis suspensions might be a case in point. Any manufacturer can introduce the occasional misfit but this rating might give you the confidence to consider a later model edition or an alternative model from the same marque – or satisfy your general misgivings and encourage you to look elsewhere!
Car Type Ratings
Depending on your vehicle these can make you rue the day you bought it or hopefully give you a warm glow! Find out how your present or potential car lines up against its competitors in key reliability areas – the lower the figure the better the reliability, the higher the figure the more the likelihood of frequent or costly repairs.
