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 2018 Lincoln MKZ in the United States are 13,555 units [1]. If the total number of problems reported by Lincoln MKZ owners in the last 8 years is 36, and the age of the vehicle is 8, the PPMY index can then be calculated as
PPMY Index = 36 / 13,555 / 8 * 1000 = 0.33.
