Car Price Tracker
New

The extension is now on the Chrome Web Store

Add it from the Chrome Web Store in one click — it works in Edge and Brave too. It updates itself, so there are no more ZIPs to download. A Firefox Add-ons listing is on its way.

Installed it by hand? That copy won't update — switch to the store version and remove the old one so listings aren't sent twice. Version 1.7 also imports every car on an Auto Trader search page at once — see what's new.

Car & Classic

  • SiteListings from Car & Classic are tracked alongside Auto Trader, with prices kept in their own currency (often euros) and mileage in the unit the seller gave.
  • ExtensionThe extension reads Car & Classic listing and search pages. Browsing a search saves it, so every page of results gets tracked, not just the ones you looked at.
