Facebook Marketplace has become the largest peer-to-peer used car marketplace in Texas. Millions of listings, no listing fees, and direct communication with sellers make it genuinely useful for buyers. But the same features that make it convenient also make it a playground for scammers. Here are the five most common used car scams on Facebook Marketplace in Texas and how to protect yourself.
1. Odometer rollback
How it works: The seller physically rolls back the odometer or replaces the instrument cluster with a lower-mileage unit. A 150,000-mile truck becomes a 75,000-mile truck overnight. In Texas, this is a federal crime under the Motor Vehicle Information and Cost Savings Act, but enforcement is difficult when the car changes hands privately.
Red flags: Unusually low mileage for the vehicle age. A 2015 truck with 30,000 miles should make you suspicious unless the seller can explain it. Excessive wear on the steering wheel, pedals, and driver seat that does not match the stated mileage. New instrument cluster or dashboard that looks newer than the rest of the interior.
How EstimateProof catches it: Every time a vehicle title is transferred in Texas, the odometer reading is recorded. EstimateProof pulls these readings from state records and flags any time the mileage goes down or jumps in a way that does not match the timeline. You see every recorded reading, in order, with dates.
2. Title washing
How it works: A car is totaled in one state and given a salvage or flood title. The scammer then re-registers the vehicle in a state with lax title laws, where the brand may not carry over. The car ends up with a clean title and gets sold to an unsuspecting buyer in Texas. This is called title washing because the salvage or flood brand gets "washed" away.
Red flags: The car was recently registered in another state, especially states known for easy title transfers. Fresh undercoating or paint that could hide flood or collision damage. Musty or mildew smell in the cabin. Sand or silt in crevices, under seats, or inside the trunk spare tire well. Prices that seem too good for the year and mileage.
How EstimateProof catches it: The report queries NMVTIS, the National Motor Vehicle Title Information System, which tracks title brands across all 50 states. Even if the current Texas title is clean, a prior salvage brand in another state will appear in the report.
3. Curbstoners
How it works: A curbstoner is an unlicensed dealer posing as a private seller. They buy cars at auction — often with known problems — do minimal cosmetic repairs, and flip them on Facebook Marketplace as if they are selling their personal vehicle. In Texas, selling more than four vehicles in a year without a dealer license is illegal under the Texas Occupations Code.
Red flags: The seller has multiple vehicles listed for sale at the same time. They want to meet in a parking lot instead of their home. The title is not in their name — they claim they are selling for a friend or family member. They rush the transaction and push for cash. The car was recently purchased at auction (visible in title history).
How EstimateProof catches it: The title history in an EstimateProof report shows every owner and transfer date. If the car was acquired at auction two weeks ago and is already for sale as a "personal vehicle," that pattern is visible in the data.
4. Deposit scams
How it works: The listing shows a desirable car at a below-market price. The seller claims to have many interested buyers and asks for a deposit — usually via Zelle, Venmo, or CashApp — to hold the car. Once you send the money, the seller disappears or blocks you. The listing may use stolen photos from a legitimate sale.
Red flags: The price is too good. The seller refuses to video call or meet in person before taking a deposit. They insist on payment apps that cannot reverse transactions. The listing photos look overly professional or have watermarks from another site. The seller claims to be out of town, in the military, or otherwise unable to meet.
How to protect yourself: Never send money before seeing the car and verifying the VIN in person. Ask the seller to send a photo of the VIN plate and run a report before you even schedule a visit.
5. Phantom listings
How it works: The car in the listing does not exist — or it exists but the person posting is not the owner. Scammers copy photos and descriptions from legitimate listings on other platforms and repost them on Facebook Marketplace at a slightly lower price. The goal is to collect your personal information or lure you into a deposit scam.
Red flags: Reverse image search shows the photos on other sites. The listing description is copy-pasted from another platform with leftover formatting. The seller cannot answer basic questions about the car, like when the oil was last changed or what tires are on it.
How to protect yourself: Always insist on a video call showing the car and the VIN plate before meeting in person. Run the VIN through EstimateProof before you drive across town.
The bottom line
Facebook Marketplace is a legitimate place to buy a used car in Texas. But the platform does almost nothing to verify sellers or listings. Your best defense is data: run the VIN before you see the car, verify the title history, and check the odometer readings. A $25 EstimateProof report is the cheapest insurance you can buy against a $5,000 mistake.
