For major things, I try to look at Consumer Reports.
I don’t think they’re padded; I do think they are up-front about what they are evaluating products on and what they award points for, and their reviews reflect that.
For instance, kevbo’s example of the Jeep Wrangler: I don’t think that it’s bias, but that they’re sticking to their evaluation criteria, which show (for instance) that the Wrangler has a rough ride, is not very fuel-efficient, is drafty, doesn’t have much cargo capacity, and the like. Well, all of those things are true, but they kind of miss the point; if you’re seriously considering buying a Wrangler, you’re not making the decision based on gas mileage and cargo capacity.
And they’re notoriously short-sighted in computers, but I think that has to do with the difficulty of predicting maintenance costs in any specific case. But again, that’s not an inappropriate slant; they tell you what they’re evaluating the computers on, and if their criteria are missing an important point or two, well, you can read their methodology and notice it.
So, to summarize: I don’t think they’re padded or skewed intentionally, but the things they evaluate the product on are not necessarily the things you might consider important, so you need to read the methodology too. And yes, I do read them for major purchases.
