That's the same reason why I was worried when I started watching that video originally. Vehicle History does not ask for any money or information, other than the VIN to check. I'm not sure how they are making money, not a bunch of ads, or information entered, but it works.
Here is a random car available for sale near me (alphabetically the first one that came up LOL). The auto trader listing states "Really nice local Washington State trade-in that has been well maintained." Actually looking up that vin, shows a different story.
