📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Chevrolet Astro 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 Astro 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 Chevrolet Astro 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 Astro Model Years

Astro Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2005	10	30,257	18	0.02
2004	16	29,150	19	0.03
2003	67	46,804	20	0.07
2002	76	50,768	21	0.07
2001	91	51,638	22	0.08
2000	179	109,856	23	0.07
