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 2008 Lexus GS in the United States are 19,250 units [1]. If the total number of problems reported by Lexus GS owners in the last 17 years is 17, and the age of the vehicle is 17, the PPMY index can then be calculated as
PPMY Index = 17 / 19,250 / 17 * 1000 = 0.05.
