What scam is this?

So I email him and get this response:

Hello, I was reaching out to you about your vehicle for sale. Do you have a current vehicle history report for it? If not, I suggest getting one at:
SafeVinCheck.com
When I was selling my vehicle I got one from there to show people that were interested. It was only $19 which is half the cost of Carfax($40 or more). It will show if there are any issues with it. The peace of mind it gives for such a large sale is a bonus too.
It will verify that it has not been in any bad accidents, that it has a clean title and that it has not been stolen. There are so many scams out there. People are more likely to look at it with a report provided.
Talk to you soon. Thanks!
