Consumer Reports has been
Consumer Reports has been biased in favor of Japanese cars for years. The problem with their ratings (and Consumer Reports is a poor choice for car information or ratings) is that you have no idea of the respective sample sizes. All CR does is send out a survey to its subscribers and hope that they answer honestly - and that they answer.
Think about it. Lincoln sells about 85,000 cars a year, Toyota around 2 million (and Lexus about 250,000). CR has about 7 million subscribers. Typically about 40% of surveys are returned, meaning about 2.8 million people responded. If statistics hold, a larger number of people own Lexus' or Toyotas, and since the magazine has been Japanese-biased for the better part of two decades, I'd be willing to bet that there were considerably more surveys returned from Toyota/Honda than Lincoln/Cadillac, which means that the sample size for Lincoln was extremely small and probably not large enough to really be indicative of brand quality.
Until CR actually releases how many cars were in each sample, CRs surveys will be worthless.
