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 2003 Lexus LX in the United States are 8,491 units [1]. If the total number of problems reported by Lexus LX owners in the last 19 years is 3, and the age of the vehicle is 19, the PPMY index can then be calculated as
PPMY Index = 3 / 8,491 / 19 * 1000 = 0.02.
