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 2014 Audi A4 in the United States are 37,314 units [1]. If the total number of problems reported by Audi A4 owners in the last 12 years is 91, and the age of the vehicle is 12, the PPMY index can then be calculated as
