The 10 Best Automobile Brands in 2000
by James Bleeker
This page provides two rankings of the 10 best brands of automobiles sold
in North America from model year 1992 to 1999. Each ranking employs a different method of computation.
The statistics used in the computations for rating and ranking the brands are those found within the April
2000 issue of Consumer Reports. The two sections providing the necessary statistics are CR's Used-Cars-To-Avoid list and its reliability charts. Reliability is defined by the magazine as the infrequency of serious problems, which it measures annually by a subscriber survey.
The first ranking of the car brands is based on each brand's infrequency of trouble-prone models. This ranking provides a measure of how successfully each brand's models avoided the bottom end of the model-quality spectrum.
The second ranking of the car brands is based on the average of the overall reliability ratings of each brand's models. The second ranking provides a measure of how well a brand's models performed over the entire model-quality spectrum.
Auto Brand Quality by Frequency of Trouble-Prone
Models: The Top 10 of 2000
To form a brand-quality measure from the 2000 list of Used Cars To Avoid, the first step is to count each brand's entries on the list. Each model year of each model is treated as a separate entry.
Next, as the number of automobile models sold under a brand name varies
greatly from brand to brand, it is necessary to take account of the fact
that a brand with more models has a greater opportunity to have more model
years of low quality. To compensate for a possibly inflated, or deflated,
frequency of trouble-prone model years within a brand, as well as a
variability in model data sufficiency, the number of a brand's entries in
CR's 2000 Used-Cars-To-Avoid list is divided by the total number of overall reliability ratings for the brand found in the reliability charts of the same issue of Consumer Reports. The overall reliability ratings are found in the
Reliability-Verdict row of the 2000 reliability charts.
By the method of computation, this quality measure begins with 0 and may run to a value some greater than 1. The value of 0 is the highest quality rating attainable by a brand and is achieved only when a brand has no entry on the Used-Cars-To-Avoid list.
The 10 best car brands by the foregoing computations, together with their quality ratings, are given in the
first bar graph below. Only those brands with at least 5 overall CR reliability ratings are included.
Auto Brand Quality by the Average of Overall Reliability Ratings:
The Top 10 of 2000
To compute brand-quality ratings and assemble a brand-quality ranking
using Consumer Reports' overall reliability ratings, a number is associated
with each rating. A +1.0 is ascribed to a rating of Better Than Average, a 0 to a rating of Average,
and a -1.0 to a rating of Worse Than Average. Then an average is taken over all of the brand's model years and models offering an overall reliability rating. CR's
2000 overall reliability ratings are found in the Reliability-Verdict row of its reliability charts
and are limited to three grades - Better Than Average, Average, and Worse
For this measure of quality, the range is from -1.0 (the worst possible) to +1.0 (the best possible).
The 10 best car brands by this set of computations, together with their quality ratings, are given in the
second bar graph below. Only those brands with at least 5 overall CR reliability ratings are included.
The Bar Graphs of the Top 10 of
In both of the graphs that follow, the order of the car brands is with the
best on top.
When two or more brands have no entry in CR's list of Used
Cars To Avoid, the brands are listed in descending order of
number of overall reliability ratings (a brand with a greater
number of overall reliability ratings appears above a brand with
fewer ratings), as those brands with a greater number of ratings
would have a greater opportunity for a trouble-prone model year
to be found.
Summary and Analysis
By infrequency of trouble-prone models (first graph), the
ten best brands in 2000 were, in descending order (best first), Toyota Motor
Corporation's Toyota, Toyota's Lexus, Honda Motor
Company's Acura, Fuji Heavy Industries' Subaru, BMW, Nissan's Infiniti,
Suzuki, Volkswagen's Audi, Nissan Motor Company's Nissan, and General
By overall unreliability (second graph), the ten best
brands in 2000 were, in descending order (best first), Nissan's Infiniti,
Toyota's Lexus, Honda's Acura, Toyota's Toyota, Fuji's Subaru, Honda's
Honda, Nissan's Nissan, BMW, Suzuki, and Mazda.
There are 8 brands common to both best-10 lists; they are:
2 Toyota brands - Toyota and Lexus
Worthy of note is that there is only one Big Three brand in
the Top 10 by infrequency of trouble-prone models and no Big
Three brand in the Top Ten by overall reliability.
