📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Oldsmobile Silhouette of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across Silhouette model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.

PPMY = P / S / Y * 1000,

where P = total problems reported during the life of a Oldsmobile Silhouette model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).

The results are shown in Table 3.

Table 3. Use PPMY Index to Compare Reliability Across Silhouette Model Years

Silhouette Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2004	12	9,420	19	0.07
2003	39	18,330	20	0.11
2002	102	23,865	21	0.20
2001	111	36,278	22	0.14
2000	138	41,706	23	0.14

📊 Number of Problems Reported During the First Year
