I think that is starting to change. You have 5 or 6 major auction houses roving the country each selling 2-300 or more cars each month. Not to mention the all around auction houses like Christies that are doing very high end stuff. They are getting heavy TV advertising and coverage. The auction is basically becoming mainstream for most cars, which is leaving Craigslist with the subpar cars and fixer-uppers.
They were advertising a Corvette only auction with over 400 Corvettes, that is some serious movement if they sell 60-75% of them.
