We have partnered with a number of top car classified sites, like Cars.com, eBay, and CarsDirect, to show their listings on our results page. Unlike those sites though, we have no affiliation with craigslist or AutoTrader.
To provide you access to craigslist results, we link to our
partner site, SearchTempest.com. We built SearchTempest (which also is NOT affiliated with craigslist) to let anyone search multiple craigslist cities at once, as well as other sites like eBay, Amazon, and Oodle. It works for other stuff besides cars, but for AutoTempest, we link you directly to a car results page matching your search.
For AutoTrader, we simply provide a link to an AutoTrader results page matching your search on AutoTempest.com.
