The 10 Most Reliable and Durable Cars of Model Year 1984 This page lists the top ten cars of model year 1984 by reliability-and-durability grade point average (Reliability-Durability GPA or more concisely, R-D GPA). 1984's Top 10 Cars These 10 car classics are listed below in descending order of Reliability-Durability GPA (best first). The equipment of each model is that offered in the U.S.
As in 1983, Honda dominated 1984's list of the best, accounting for 4 of the Top 10. 1984 was the third year that one or more vehicles by Nissan Motor Company made the list. Toyota Motor Corporation and Daimler-Benz AG had automobiles that made the Top 10 every year from 1975 to 1984. The Toyota Pickup made the Top 10 list every year since 1975, the Mercedes-Benz 300D made the best list every year save 1981, and the Toyota Cressida made the list of 10 best every year since 1978, save 1982. Note the very small difference in Reliability-Durability GPA among the Top 10, but the rather large range of base prices. By 1984, there appears to be no relationship between engineering excellence and price; the old adage "You get what you pay for" had no application in automobiles. Manufacturers of the Top 10 Honda Motor Company accounted for 4 of 1984's best, same as in 1983 and up from 3 in 1982. Toyota Motor Corporation accounted for 3 of the most reliable and durable cars of 1984, an increase from 2 in 1983, but a decrease from 4 in 1982, 8 in 1981, 6 in 1980, 5 in 1979 and 1978, and 4 in 1977, 1976 and 1975. Although Toyota's rapid expansion of product offerings likely made quality control more challenging even in the early 1980s; nonetheless, Honda did a very fine job of displacing Toyota as leader of the Top 10. Nissan Motor Company accounted for 2 of the best in 1984; Daimler-Benz AG accounted for one. Japanese-built cars accounted for 9 of 1984's best cars, up from 7 in 1983; German-built cars accounted for the remaining 1, down from 3 in 1983. Note that in 1984 (as in 1983, 1982, 1981, 1980, and 1979) none of the Detroit 3 had a car among the Top 10. The following chart gives each car maker's percent share of the Top 10 of 1984.

Computations
To compute the reliability-durability grade point average of the MY 1984 cars, Consumer Reports' reliability ratings for the age ranges 4-to-5 years and 5-to-6 years are used. 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, for each age range, 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, the average for the two age ranges is taken. The BMW 528e, 533i, the Toyota 4Runner, the Isuzu Pickup 2wd, the Toyota Land Cruiser, and the Toyota Tercel Wagon 2wd offered only one age range of data.
