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 2011 Lexus LS in the United States are 9,762 units [1]. If the total number of problems reported by Lexus LS owners in the last 14 years is 13, and the age of the vehicle is 14, the PPMY index can then be calculated as
PPMY Index = 13 / 9,762 / 14 * 1000 = 0.10.
