I see this publisher is using some very interesting javascript. http://www.motortrend.com/offers.html I noticed it in my logs as I use adwords , I occasionally check referring links. I am not happy that the ads seem masked and the page has well, pretty much zero content, especially with a name like offers.
only thing i can think of is that they might be a premium publisher. it looks to be a well maintained site and has a not bad alexa ranking
