📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Ford Thunderbird 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 Thunderbird 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 Ford Thunderbird 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 Thunderbird Model Years

Thunderbird Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2005	34	9,208	19	0.19
2004	38	12,583	20	0.15
2003	35	14,016	21	0.12
2002	106	28,821	22	0.17

📊 Number of Problems Reported During the First Year
