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 Lincoln Navigator in the United States are 10,485 units [1]. If the total number of problems reported by Lincoln Navigator owners in the last 15 years is 22, and the age of the vehicle is 15, the PPMY index can then be calculated as
