AutoTempest

AutoTempest is a used car search engine that gathers listings from multiple marketplaces into one search, reducing the need to visit each site separately. It aggregates dealer and private-seller listings from sources including eBay Motors, Cars.com, TrueCar, Carvana, and Cars & Bids, and generates comparison links for large sites it does not have partnerships with. The service has operated since 2008.

Searches support extensive filtering across attributes such as fuel type and interior color, with local or nationwide scope. Results can be browsed by source or combined into a single list, with standard sorting options. AutoTempest works in a browser on any device and is also available as an iOS and Android app. It covers both used and new cars, with new-car search supported through a partnership with TrueCar. Sellers can list vehicles through partner sites, which then appear in AutoTempest searches.

The service is aimed at car buyers searching across many listings at once, from daily drivers to specialty vehicles. The pages do not describe a free plan, trial, editions, or seat-based or usage-based pricing.
