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 2006 Lexus LS in the United States are 17,220 units [1]. If the total number of problems reported by Lexus LS owners in the last 16 years is 25, and the age of the vehicle is 16, the PPMY index can then be calculated as
PPMY Index = 25 / 17,220 / 16 * 1000 = 0.09.
