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 2002 Lexus IS in the United States are 24,079 units [1]. If the total number of problems reported by Lexus IS owners in the last 20 years is 19, and the age of the vehicle is 20, the PPMY index can then be calculated as
PPMY Index = 19 / 24,079 / 20 * 1000 = 0.04.
