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 BMW M5 in the United States are 1 units [1]. If the total number of problems reported by BMW M5 owners in the last 20 years is 50, and the age of the vehicle is 20, the PPMY index can then be calculated as
PPMY Index = 50 / 1 / 20 * 1000 = 2500.00.
