This page has been updated to include the data that became available in 2007.

A model's Reliability Percentrank is a ranking of that model's Reliability Score relative to all other Reliability Scores for the given model year and age range. The percentrank was computed using the Percentrank function of Microsoft's Excel 2002 and, as the first part of the compound word percentrank suggests, is a value between 0.00 and 1.00. If a model's Reliability Percentrank is near 0.00, it has a very low Reliability Score, and if a Percentrank is near 1.00, it has a high Reliability Score. For a more detailed explanation of Reliability Percentranks and Reliability Scores, click here to be taken to the Methodology page.

Note that Reliability Percentranks for model year 2004 are based on one year of data. Consequently, the Reliability Percentranks for individual models of that year are more subject to statistical fluctuation. These early data have been provided as several visitors have expressed interest in more current Percentranks; however, a better guide to the reliability of a new model are likely the five-year averages.

To view charts of the Reliability Percentrank averages for the Mercury line and an extrapolation of these averages to 2004, 2005, 2006, 2007, 2008, and 2009, and individual charts of the Reliability Percentranks for seven of the models of the Mercury line and an extrapolation of the Reliability Percentranks of two of these models to 2004, 2005, 2006, 2007, 2008, and 2009, click here.
