Know exactly what you’re buying.

Guides, tools, and investigations that protect used car buyers from fraud, hidden damage, and bad deals. How each scam works, what to check before you pay, and what the law in your state gives you when a sale goes wrong.

Start with the VIN

Enter any 17-character VIN. You get the factory build data, every NHTSA recall for that model year, owner complaint counts and crash-test ratings, read straight from the government databases.

The free check does not cover mileage, accidents or title brands; a paid vehicle history report does. A report is worth the money for some cars and not for others, and we explain when to buy one.

Pick your path

Three reading lists, one for each kind of visitor. Each answers the questions people actually arrive with.

First-time buyer

You’ve never bought a used car, or never checked one properly. Start at the top and read down.

  1. What is a VIN and what does it tell me?
  2. What does a free VIN check show, and what doesn’t it?
  3. The most common ways used-car buyers get scammed
  4. What to check on the car before you hand over money
  5. Questions to ask the seller, and the answers that are red flags
  6. How to pay and transfer the title safely

Experienced buyer

You know the basics. You want the things the report doesn’t catch and the rules that change by state.

  1. Spotting an odometer rollback the report missed
  2. How title washing works and how to detect it
  3. What a salvage or rebuilt title means for value and insurance
  4. Buying from another state or importing a car
  5. Which history report is worth paying for, and what they miss
  6. Checking open recalls and whether they were actually fixed

Professional & investigator

Dealers, inspectors, investigators and r/VINvestigators regulars. Patterns, data and law, not basics.

  1. Fraud patterns active right now: curbstoning
  2. What recent prosecutions show about how schemes run
  3. The yearly numbers on thefts, recalls and complaints, and what nobody counts
  4. Disclosure and record-keeping obligations by state
  5. How VIN cloning works end to end, and how it’s caught
  6. Where to report suspected fraud and what evidence is needed
