The 9 Least Reliable and Durable Car Brands of Model Year 1987

This page lists the 9 worst car brands (as well as the 15 worst car brands) of model year 1987 by reliability-and-durability grade point average (R-D GPA).

1987's Bottom 9 Car Brands: The Nine Worst

The 9 worst car brands of 1987 are listed below in ascending order of Reliability-Durability GPA (worst first), together with their corresponding R-D GPA and Grade.

  • Hyundai line, with a Reliability-Durability GPA of 0.24 and a Reliability-Durability Grade of F
  • Jeep line, with a Reliability-Durability GPA of 0.78 and a R-D Grade of D
  • Pontiac line, with a Reliability-Durability GPA of 0.88 and a R-D Grade of D
  • Buick line, with a Reliability-Durability GPA of 1.13 and a R-D Grade of D
  • Ford line, with a Reliability-Durability GPA of 1.39 and a R-D Grade of D
  • Oldsmobile line, with a Reliability-Durability GPA of 1.47 and a R-D Grade of D
  • Chevrolet line, with a Reliability-Durability GPA of 1.52 and a R-D Grade of low C
  • Dodge line, with a Reliability-Durability GPA of 1.57 and a R-D Grade of low C
  • Chrysler line, with a Reliability-Durability GPA of 1.61 and a R-D Grade of low C
The Reliability-Durability GPAs of 1987 generally run higher than those of 1986.  The fact that the Reliability-Durability GPAs of 1987 are based on reliability ratings for the age range 4-to-5 years, rather than reliability ratings for the age ranges 4-to-5 years and 5-to-6 years, likely accounts for much, if not all, of the increase. See computations below.

This is a bar graph of the Reliability-Durability GPAs of the 15 best car brands of model year 1987. The Reliability-Durability GPA of a car model is a composite measure based on the category and overall reliability ratings of Consumer Reports for age range 4-to-5 years. Brand R-D GPA is an average of model R-D GPAs. Chart by James Benjamin Bleeker, 6 June 2012.

The Reliability-Durability GPAs of 1987 generally run higher than those of 1986.  The fact that the Reliability-Durability GPAs of 1987 are based on reliability ratings for the age range 4-to-5 years, rather than reliability ratings for the age ranges 4-to-5 years and 5-to-6 years, likely accounts for much, if not all, of the increase.

This is a pie chart of each country's share of the 15 worst car brands of model year 1987 by Reliability-Durability Grade Point Average (GPA). The Reliability-Durability GPA of a car model is a composite measure based on the category and overall reliability ratings of Consumer Reports for age range 4-to-5 years. Brand R-D GPA is an average of model R-D GPAs. Chart by James B. Bleeker, 7 June 2012.

The U.S. has a much greater dominance of the worst 15 car brands (accounting for 80% of the worst 15 brands) than Japan has of the best 15 car brands (accounting for only 60% of the best 15 brands).
Computations

To compute the reliability-durability grade point average of the MY 1987 cars, Consumer Reports' reliability ratings for the age range 4-to-5 years are used. For the R-D GPAs for model year 1975 to 1986, Consumer Reports' reliability ratings for the age ranges 4-to-5 years and 5-to-6 years are used. The reason for the difference is that CR did not provide an overall reliability rating (a component in the computation of the Reliability-Durability GPA) for much of the 1990s and the first half of the 2000s.

CR's ratings are converted to numerical values following the standard academic pattern: a grade point of 4.0 (an A) is accorded a rating of Much Better Than Average, a 3.0 (a B) is accorded a rating of Better Than Average, a 2.0 (a C) is accorded a rating of Average, a 1.0 (a D) is accorded a rating of Below Average, and a 0 (an F) is accorded a rating of Much Below Average.

Then, the grade point of CR's overall reliability rating is weighted 2/3 and the average of the grade points of the category ratings is weighted 1/3.

Finally, a car brand's Reliability-Durability GPA is computed by taking the average of the Reliability-Durability GPAs of its models.
