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 2007 Subaru Legacy in the United States are 16,871 units [1]. If the total number of problems reported by Subaru Legacy owners in the last 17 years is 45, and the age of the vehicle is 17, the PPMY index can then be calculated as
PPMY Index = 45 / 16,871 / 17 * 1000 = 0.16.
