SnagFor dealers & car flippers
Find underpriced cars before anyone else.
The best private-party cars sell in hours. SnagSonar watches Facebook Marketplace around the clock and pings your phone the moment a car in your buy box goes live — at a fraction of what dealer sourcing tools charge.
Instant car alerts
Checks as often as every 15 seconds, so you message the seller while everyone else is still refreshing.
Year, mileage & price filters
Set the exact years, max mileage and price range you buy. Everything else stays out of your feed.
Free VIN check
When a listing includes a VIN, SnagSonar decodes it with official NHTSA data and checks for open recalls — no extra cost.
Title-status flags
Salvage and rebuilt titles get flagged from the listing text, and one toggle skips them entirely.
Typical price on every car
Each listing shows what similar cars nearby are asking, so under-market stands out at a glance.
Price-drop alerts
A seller getting impatient is your opening. Get pinged when a matched car's price comes down.
From alert to driveway.
Set your buy box
“Tacoma 4x4, 2010 or newer, under 120k miles, under $15,000, within 40 miles. Skip salvage.” One search per model you buy.
Your phone buzzes first
A matching truck goes live and the alert lands with the price, mileage, distance and the typical asking price for similar ones nearby.
Check it in seconds
Title status flagged, VIN decoded, open recalls listed, seller's other listings a tap away. Decide while other buyers are still typing “is this available?”
Message with a number
One-tap templates send a real offer and a pickup time. First serious message usually wins the car.
SnagSonar never logs into your Facebook account and never messages anyone for you. It watches public listings and alerts you — you message sellers yourself, like any other buyer.
