For well over a year I have been watching the Q7 TDI's up for sale. I've been waiting for the "right one" to come along and for whatever reason over the past 3 or so months the 2011 and somewhat the 2012 Q7 TDIs have vanished from these sites like cars.com, autotrader, carmax and carguru, where's I'd been watching, plus a couple local trade sites and a craigslist scraping site.

Can anyone direct me to some new resources, aside those I mentioned above? Or is this some other reason why the 2011 and 12's been vanishing?
