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 2003 Subaru Baja in the United States are 15,827 units [1]. If the total number of problems reported by Subaru Baja owners in the last 22 years is 46, and the age of the vehicle is 22, the PPMY index can then be calculated as
PPMY Index = 46 / 15,827 / 22 * 1000 = 0.13.
