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 2013 Audi TT in the United States are 2,190 units [1]. If the total number of problems reported by Audi TT owners in the last 9 years is 3, and the age of the vehicle is 9, the PPMY index can then be calculated as
PPMY Index = 3 / 2,190 / 9 * 1000 = 0.15.
