What is your favourite vehicle comparison website?

[CanmoreOrLess]

I am looking at buying two new or nearly new vehicle in 2012, trying to compare the leading contenders. One site (cars123 I think) only had Subaru Outbacks up to 2008, none seem to have interior noise levels (which are really important).

Which website is your go-to site for comparing vehicles?

Edmunds.com is ok

The Edmunds car comparisons page is what I use to check specs, it's the most complete I've ever found.
For general dirving impressions, I like the X vs Y type comparisons that the magazines do, but you have to take all that stuff with a grain of salt, none of them are unbaised.

Also, one someone non-traditional source is the cnet reviews. They are mostly looking at the tech, but there are usually some useful comments on general driving impressions.
