xcel,
I may be the owner of the site, but I also own a Prius and am inherently biased. I'm sure you don't want to tell the owner of the site to stop posting, too, eh?
Honestly, though, as a professional Internet developer, their website is not cross-browser compatible. I have to switch to IE to use it. Furthermore, they DO hide numbers (for instance, I had to look for an outside resource to find the EPA for the CVT Insight).
