Excellent find! I would report it to the Chicago PD, but not alert AutoTrader because they must approve every single ad. I recently used AutoTrader to sell my car and they took about 24 hours to approve my ad, which means they should've caught and reported this themselves. It appears to me that they are complacent in such activities and need to be investigated themselves.

@Newfind OP you should be able to add this to your initial post, but alas you did a direct link. Too bad, and another reason to not do direct links - no ability to update. I think the fact that Auto Trader MUST approve every ad is extremely important.
