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 2010 Audi A3 in the United States are 2,454 units [1]. If the total number of problems reported by Audi A3 owners in the last 13 years is 59, and the age of the vehicle is 13, the PPMY index can then be calculated as
PPMY Index = 59 / 2,454 / 13 * 1000 = 1.85.
