Before you do much crawling of car dealer websites, you should talk to the companies who build the sites. (Dealer.com/Vinsolutions..etc) They have systems in place that package up the car listings for their dealers and send them in csv/xml format to many sites like Autotrader/Cars.com on a daily basis.
no kidding?! That would make my life soooooooo much easier. If you have any contacts would be stoked to make the connection - my email is dw5ight@gmail.com, else I'll shoot them a line and see if anyone wants to talk to two guys in an apartment :P Thanks!
