Here's more info than you want to read on how Consumer Reports compiles their survey results. Most of it sounds good but, when I had a subscription, I didn't agree with a lot of their results and felt they strictly cared about reliability/repairs so a great car with a problem or two dropped way down while a more reliable car that sucks at acceleration, ride, handling, comfort, etc could move way up.
Granted, they aren't reviewing cars, just rating certain criteria so their methods do show those criteria such as reliability, cost, ranking, etc. 640,000 responses from subscribers to survey requests is a solid number. Much higher than most car surveys, IMO.
It's hard to argue with subscribers accurately reporting their experiences. I tried to accurately fill out the survey when they sent it (it's long). Still, I disagreed with the survey results often. 'Mint would say I was wrong and biased so judge it for yourself.
