2012's Best Luxury Cars Sold in North
America:
Table and Charts
by James Bleeker
This page provides the table giving the 2012 Auto Reliability GPAs of the
best luxury cars in 2012, a chart of manufacturer shares of the best in 2012, and a chart
depicting the Overall Reliability GPAs of the top 5 luxury cars in 2012
and 10 worst luxury cars in 2012.
The Table
The table below provides the Auto Reliability GPAs and Grades of the best of
the luxury cars sold in the U.S.
Reliability GPAs for 4 age ranges are given so that the
visitor may examine more closely the age range that is of
greater interest to him or her. As well, an Overall Reliability GPA - an
average of the 4 Reliability GPAs - is provided; this may be of greatest
value to those interested in purchasing a new car and owning it for decade,
or several.
Letter grades for automobile reliability are determined thusly: A if the Auto Reliability GPA is 3.50 to
4.00, B if the Auto Reliability GPA is 2.50 to 3.49, C if the Auto Reliability GPA is 1.50 to 2.49, D if
the Auto Reliability GPA is 0.50 to 1.49, and F if the Auto Reliability GPA < 0.50.
The cutoff for the list of the best in 2012 is an Overall Auto Reliability GPA of 2.75, a
modest B by letter grade. The list is in descending order of Overall GPA, i.e.,
from best to worst.

| Note: To be among the Best of 2012, the Overall
Reliability GPA must be based on at least 3 model years of
data. |
Note that among these better vehicles in 2012, there is not one by
General Motors Corporation, the Chrysler Group, or Ford Motor Company.
The manufacturers which have offered one or more of the least trouble prone
luxury cars in 2012, as reported by Consumer Reports subscribers and
measured by the Overall Reliability GPA, are Toyota Motor Corporation (with
3 of the 5 best), Nissan Motor Company, and Honda Motor
Company.
Again Toyota and Honda dominate the best list.

Caution |
When the number of model years of
data (appearing in the far right column) for a vehicle
is limited to more recent years, the reliability GPAs,
Average GPA, and Minimum GPA of that vehicle may be less
reflective of the vehicle's reliability over a longer
period of time. |
The Auto Reliability GPAs are automobile reliability
statistics that are obtained from Consumer Reports' auto reliability
survey data summarized in the reliability tables of (1) Consumer Reports: New Car
Buying Guide: 2012, (2) Consumer Reports: Used Car Buying Guide: 2012, and
(3) the April 2012 issue of the Consumer Reports magazine.
The method of computation of the GPAs is probably familiar to nearly every college, technical school, and high school student.
A Grade Point of 4.00 (that is, an A) is given to a Consumer Reports Used Car Verdict
of "Much Better Than Average," a GP of 3.00 (that is, a B) is given to a CR
"Better Than Average" rating, a GP of 2.00 (that is, a C) to an "Average"
rating, a GP of 1.00 (that is, a D) to a "Worse Than Average" rating, and a
GP of 0.00 (that is, an F) to a "Much Worse Than Average" rating. A
4-year Grade
Point Average (GPA) is an average of the Grade Points and is computed using
Microsoft's Average(a:b,[c:d],...) function. The Overall GPA given in the
table and chart above is the average of the four 4-year GPAs.
