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 2012 Lexus ES in the United States are 32,739 units [1]. If the total number of problems reported by Lexus ES owners in the last 14 years is 35, and the age of the vehicle is 14, the PPMY index can then be calculated as
PPMY Index = 35 / 32,739 / 14 * 1000 = 0.08.
