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 2004 Volvo C70 in the United States are 8,421 units [1]. If the total number of problems reported by Volvo C70 owners in the last 18 years is 19, and the age of the vehicle is 18, the PPMY index can then be calculated as
PPMY Index = 19 / 8,421 / 18 * 1000 = 0.13.
