I used to read several of them (Automobile, Autoweek, Road and Track, Motor Trend, Car and Driver), but they only seemed to raise my blood pressure with how much I disagreed with their opinions on cars. They aren't critical enough, and seem to be willing to forgive anything on cars which have the proper nameplates.
I will still go the websites for performance statistics, and some spy shots, but I stay away from the articles unless I'm in a fighting mood.
