In our research we use the PPMY index to compare the reliability of vehicles. The PPMY index of a certain model is defined as the problems reported per thousand vehicles per Year. The total sales of the 2010 Subaru Impreza in the United States are 37,992 units [1]. If the total number of problems reported by Subaru Impreza owners in the last 13 years is 61, and the age of the vehicle is 13, the PPMY index can then be calculated as
PPMY Index = 61 / 37,992 / 13 * 1000 = 0.12.
