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 2009 Mazda CX-7 in the United States are 12,745 units [1]. If the total number of problems reported by Mazda CX-7 owners in the last 17 years is 86, and the age of the vehicle is 17, the PPMY index can then be calculated as
PPMY Index = 86 / 12,745 / 17 * 1000 = 0.40.
