Whenever someone asks me how to safely buy a used car, I tell them: “Start with a VIN check.” I personally use https://cleanautohistory.com/en/product/carfast-express , and it’s been a game-changer. It tells you the whole story—accidents, theft, title issues, and even mileage fraud. I avoided buying a car with a shady past just because this tool flagged something I wouldn’t have caught otherwise.
