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 2001 Mazda 626 in the United States are 51,386 units [1]. If the total number of problems reported by Mazda 626 owners in the last 21 years is 228, and the age of the vehicle is 21, the PPMY index can then be calculated as
PPMY Index = 228 / 51,386 / 21 * 1000 = 0.21.
