Scams are common in the used car market, but a simple vehicle history report can reveal the truth behind the deal. By knowing the most common tricks and how to spot them using a VIN check, you can protect yourself from costly mistakes and fraudulent sellers.
Odometer Fraud
Odometer fraud happens when a seller tampers with a car’s mileage to make it appear far less used than it really is. A car with a lower odometer reading is often worth more money, so some sellers illegally “roll back” the odometer or even replace it with a unit that shows fewer miles.

- You might overpay for the car.
- The vehicle could require major repairs sooner than expected.
- Warranties and service intervals could be voided or missed.
How a vehicle history report helps:
- Reports gather mileage entries from a wide range of sources, such as DMV registrations, emissions tests, maintenance records, and inspections.
- You can check that the mileage increases consistently over time.
- If the report shows an odometer reading that is lower than one reported earlier, that is a clear sign of potential fraud.
- Watch out for gaps in the mileage history or records that do not make sense given the car’s age or service dates.
Title Washing and Salvage Titles
Title washing is when a seller moves a car with a branded or damaged title to another state in order to remove that “brand” and make the title appear clean. This is illegal and is often done to hide the fact that a vehicle has been totaled (salvage), rebuilt after a major accident, or damaged by flood.
Why salvage, rebuilt, and flood titles are risky:
- These vehicles have a history of severe damage and may be unsafe or have hidden problems that are not immediately apparent.
- Insurance companies frequently declare such cars a total loss.
How scammers hide these vehicles:
- Move them across state lines where DMV systems might not communicate, so a title that says “salvage” in one state could be wiped clean elsewhere.
- Do cosmetic repairs that cover up real damage, then present the car as having a “clean title.”
How a vehicle history report helps:
- Reports include title data from multiple states. You can see if the car ever had a title brand like salvage, rebuilt, or flood, even if the current title is “clean.”
- Look for frequent or unexplained changes in title location as this is a common tactic in title washing.
- Any history of branded titles should be considered a major warning sign, even if the title looks fine now.
Recovering Stolen Vehicles
Sometimes, stolen cars are sold to unsuspecting buyers with fake documents or altered VIN plates. These vehicles may seem ordinary but could be seized if their real identity is discovered, leaving you with no car and no recourse.
Risks of buying a stolen car:
- The car could be repossessed by police at any time, with no compensation for your loss.
- You might be subject to investigation or prosecution if it appears you knowingly bought a stolen vehicle.
Warning signs:
- The VIN on the car does not match the paperwork or windshield VIN.
- The seller has suspicious or incomplete documents.
- The sale feels rushed or the price is suspiciously low.
How a vehicle history report helps:
- The report can show if a car was ever reported stolen and, in many cases, if it was later recovered.
- If a car has a theft record but no recovery record, that is a serious red flag.
- Some reports will clearly indicate if a vehicle’s VIN is associated with multiple identities or unusual activity.
Final Tips for Avoiding Used Car Scams
- Always run a VIN check and read the full vehicle history report before you buy.
- Be cautious of deals that seem too good to be true or sellers who pressure you to decide quickly.
- Ask questions about any unusual history or gaps in documentation.
- Inspect the car yourself or hire a trusted mechanic.
- Buy from reputable dealers when possible, and insist on transparency and documentation.
