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 GX in the United States are 28,995 units [1]. If the total number of problems reported by Lexus GX owners in the last 19 years is 12, and the age of the vehicle is 19, the PPMY index can then be calculated as
PPMY Index = 12 / 28,995 / 19 * 1000 = 0.02.
