Agreed, really good site for both historical trend information and real-time assessment of how good or bad a deal is. The caveat to that is sometimes they don't fully value a given trim level or option set into a deal. So a low price on a stripped down car might not be as excellent as they say, or a moderate price on a fully loaded car might be better than the "fair" or "good" that they give it. But if they say something is overpriced, it's virtually always overpriced.
