How to spot fake and misleading car listings on Facebook Marketplace
Wrong mileage, dealers posing as private sellers, bait prices and salvage titles hidden in the description — the red flags we filter out of thousands of listings a day.

We read thousands of car listings a day across Facebook Marketplace, KSL and Craigslist. A big share of the “deals” are not deals at all — they’re typos, dealers, or cars with a problem the seller buried in the description. Here’s what to look for before you drive anywhere.
1. Mileage that can’t be right
Facebook’s mileage box is a free-text field, and sellers fill it in badly. We regularly see a 2013 truck listed at “2,000 miles” when the dash in the photos reads close to 200,000, or “156” when the seller meant 156k. The listing then looks thousands of dollars under market because every value tool prices it as a low-mile truck.
- Compare the mileage to the car’s age. Most cars do 10,000–15,000 miles a year. A 10-year-old car under 15,000 miles is rare.
- Look for an odometer photo — if there isn’t one, ask for it before anything else.
- Read the description: the real number is often written there (“200k millas”, “runs great at 180k”).
2. Dealers pretending to be private sellers
Small lots and “curbstoners” (people flipping cars without a dealer license) post as individuals because private listings get more trust. Their prices are retail, not private-party, so the deal usually isn’t there.
- Financing language: “we finance”, “all credit”, “low down payment”, “financiamos”.
- Fees and taxes in the ad: “plus tax, title and doc fee”, “out the door”.
- Prices ending in 995 or 988.
- The same seller with five or more different cars listed.
- Lot backdrops, watermarks or the same photo style across many cars.
3. Bait prices
A clean, late-model car at half its value with one photo and no description is almost always a scam, a deposit grab, or a listing for parts. Real underpriced cars usually have a reason you can see: a seller who’s moving, a cosmetic issue, a car that needs a cheap repair.
4. Title and condition problems in the fine print
Read the whole description. “Rebuilt”, “salvage”, “bill of sale only”, “no title”, “needs transmission”, “doesn’t start” and the Spanish versions — “título reconstruido”, “no prende”, “para partes” — all change what the car is worth. A branded title can knock 20–40% off resale.
The short checklist
- Does the mileage make sense for the year?
- Is there an odometer photo?
- Any financing, fee or lot language?
- How many other cars does the seller have listed?
- Does the price have a visible reason?
- Did you read the whole description for title and mechanical problems?
- Run the VIN for recalls and history before you hand over cash.
