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 2018 Mini Cooper in the United States are 774 units [1]. If the total number of problems reported by Mini Cooper 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 / 774 / 7 * 1000 = 1.85.
