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 2019 BMW M5 in the United States are 3,591 units [1]. If the total number of problems reported by BMW M5 owners in the last 7 years is 10, and the age of the vehicle is 7, the PPMY index can then be calculated as
PPMY Index = 10 / 3,591 / 7 * 1000 = 0.40.
