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 2006 Subaru Impreza in the United States are 42,491 units [1]. If the total number of problems reported by Subaru Impreza owners in the last 19 years is 68, and the age of the vehicle is 19, the PPMY index can then be calculated as
PPMY Index = 68 / 42,491 / 19 * 1000 = 0.08.
