How to monitor Facebook Marketplace for car deals
Write your filters first, set up a search that checks Facebook Marketplace for you, and read each car alert against similar listings before you message the seller.
What's new
Product changes, newest first.
One sentence for each change, with a link to read more.
-
Opened listings move to a new Seen tab on Home and on each search, so New holds only what nobody on your team has opened yet. Mark as new puts one back.
-
Clear the rest hides every listing older than 2 days in one move, with one Undo.
-
Busy teams open Home on Today's best: the best-priced new listings first, grouped by how good the price is.
-
Analyze with AI on a search: say what's wrong in your own words and get up to 3 changes, each with how many listings it adds or leaves out and real listings to show it. Ask for deals and it suggests price check changes.
-
Choose how often email and Telegram alerts reach you (Instant, every 15 minutes, every hour or once a day at 08:00), for your account or one search, and set quiet hours when nothing is sent. Slack and Discord still post at once.
