Car Reliability Ratings 2010 - The 20 Best 6-to-10-Year-Old Coupes, Sedans, and Hatchbacks

Each year the consumer Union rates automobiles for infrequency of reported serious problems by model and model year. It rates a model, for each model year gift the critical data, as "Much good than Average," "Better than Average," "Average," "Worse than Average," and "Much Worse than Average." In 2010, it reported these ratings in the April 2010 issue of Consumer Reports, Consumer Reports: New Car Buying Guide: 2010, and Consumer Reports: Used Car Buying Guide: 2010.

Car Reliability Ratings 2010 - The 20 Best 6-to-10-Year-Old Coupes, Sedans, and Hatchbacks

In order to derive a four-year reliability rating for a model, consumer Union's model-year reliability ratings must first be converted to numerical values. To do this, the standard schoraly practice is followed. A letter grade of A and a grade point of 4.00 is ascribed to a "Much good than Average" rating, a letter grade of B and a grade point of 3.00 is ascribed to a "Better than Average" rating, a letter grade of C and a grade point of 2.00 is ascribed to an "Average" rating, a letter grade of D and a grade point of 1.00 is ascribed to a "Worse than Average" rating, and a letter grade of F and a grade point of 0 is ascribed to a "Much Worse than Average" rating.

To compute a 2010 car reliability rating for 6-to-10-year-old convertibles, coupes, sedans, and hatchbacks, the mean of each model's grade points for model years 2000, 2001, 2002, and 2003 is taken. This 2010 car reliability rating provides the 2010 Car Reliability Grade Point mean (Gpa) for 6-to-10-year-old vehicles.

From the foregoing, a 2010 Car Reliability Gpa must fall between 0 and 4.00 or on one of the two end values, and a higher 2010 Car Reliability Gpa for a model means a good multi-year reliability history.

With the 2010 Car Reliability Gpas for 6-to-10-year-old vehicles computed, the twenty best convertibles, coupes, sedans, and hatchbacks from the time duration 2000 to 2003 may be set forth. The Best Twenty, Twenty-three by tie, are listed below, together with their corresponding 2010 Car Reliability Gpa, and are ranked in descending order of reliability.
