The categories are weighted as to the overall importance in terms of overall reliability. It would probably be unwieldy for CR to increase the number of categories. I cannot agree with your generalization that their information is useless. > Additionally, the 'surveys' are not objective and do nothing to > account for the fact that a BMW owner may have higher expectations > than a Chevy owner, and report accordingly. > There surveys are based on quantitative data, so whether you like it or not the surveys are objective. As to there bias, that's another question. However, I know that when I bought my 1993 Mazda protege I compared it with other similarly sized and priced vehicles. When I purchased my 1996 Mercury Villager, I compared it with other minivans. When I bought my SAAB 9-5 Wagon (which, by the way, has a very good reliability record according to CR) I compared it to the Mercedes 320 Wagon, the BMW 500 series Wagons, and the Audi A-6 Wagon (much worse than average reliabilty). I didn't compare it to the Hyundai Elantra, for example. I would bet that as a class, the owners of the Mercedes, SAABs, BMWs, and Audis would all have nearly similar expectations. > Bob
