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 2002 Audi TT in the United States are 11,137 units [1]. If the total number of problems reported by Audi TT owners in the last 24 years is 41, and the age of the vehicle is 24, the PPMY index can then be calculated as
PPMY Index = 41 / 11,137 / 24 * 1000 = 0.15.
