Chrome extension
Carpool for Facebook Marketplace
Rank every car you view by what it really costs per mile you'll get out of it, and save the good ones to your Carpool lists.
For Chrome, Edge, and Brave on desktop.
Every car, ranked
Each vehicle you open on Facebook Marketplace gets a badge with its cost per remaining mile, its rating, and its rank among every car you've viewed in the last two weeks.
Save to your lists
Add a car to your current list, any saved list, or a new one in two clicks. Price, mileage, and the listing link come along.
Your lists, in a side panel
Sort and compare the cars on the page and the ones you've saved, without leaving Facebook. Signed in, it syncs with this site.
What it can see
Carpool runs only on Facebook Marketplace pages and does nothing until you agree in the side panel. Once you do, it shares the vehicle listings it scores to build Carpool's used-car market data. Signed out, your lists stay in your browser. Details are in the privacy policy.
