This article provides two methods for selecting the 7 best Car Brands sold in North America from late 2004 to 2009. The statistics used in the computations for selecting the seven best vehicle brands are those found within the April 2010 issue of Consumer Reports, likely the most respected and followed source of automobile quality information in North America. The two sections used for ranking brand quality are Consumer Reports' list of trouble-prone cars 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 Top car brands is based on each brand's infrequency of trouble-prone models. This ranking provides a measure of how well each brand's models successfully avoided the bottom end of the model-quality spectrum.
The second ranking of the Top car brands is based on the average of the overall reliability ratings of each brand's models. The second ranking provides a measure of well a brand's models performed over the entire model-quality spectrum.
