CarFlip

A read-only Chrome extension that scores used-car listings on Facebook Marketplace while you browse.

What you see

• A badge on every car card in the feed: GREAT, GOOD, OFFER, CHECK or SKIP.
• Inside a listing: CarFlip's price estimate for that model, year and mileage, a mileage check, and a plain-English CONDITION list built from what the seller actually wrote — title status, repairs the seller admits, dealer signs, price-reducing faults.
• Margin math: profit after the repairs the seller disclosed, and the offer price that would make the deal work.

How it works

• Prices come from CarFlip's own curves, built from real private-party asking prices on Marketplace across the U.S., refreshed every month. Asking prices, not sold prices.
• 105 models. When a model or year is outside our data we say NO DATA — we never guess.
• Repair estimates use a local labor-rate band for your ZIP.

What it does not do

• It does not post, message, save, like or click anything on Facebook. Read-only.
• It does not read your Facebook account, friends, messages or any other page.
• It is not affiliated with, sponsored by, or endorsed by Meta Platforms, Inc.
