Again, the police have nothing to do with Carfax. They get all their information from the insurance companies and bodyshops. Sometimes the accident is not handled by insurance, and sometimes bodyshops don't report the repairs
The Police can report that there was an accident, but that does not establish the extent of any damage if any.
If a vehicle is damage such as in a flood, there was no accident. If the vehicle was convered by insurance, the insurance company will establish that the vehicle was a total loss, pay the claim and their paperwork would normally get to Carfax. If the car is turned over to the insurance company, they will report the vehicle has being salvaged and the state will identify the vehicles a salvaged vehicle and if the vehicle is sold or registered, it will be issued a salvage title.
Unless the eBay add stated that the vehicle was never in an accident, there is no fraud and no grounds for a refund. That's why I said that he should have asked the seller if the vehicle had ever been in an accident. If he lied and said "No" then that would be grounds for a lawsuit because he lied when he was directly asked, and you would have his email, or eBay posted answer as evidence that he lied. If you did not ask, then he is not obliged to tell you anything he knows about the vehicle.
I would never buy a vehicle over the Internet without seeing the vehicle and being able to test drive it, kick the tires and know what I'm buying.
eBay and PayPal always imply that the Buyer is safe from fraud but they actually do more to protect the seller from fraud than they do the buyer. Many years ago I purchased a Mini Digital CamCorder from a seller on eBay who was listed as being in the Phoenix, AZ area. The camera was listed as brand new, but the box had been opened. When I got the camera it was missing a number of accessories, including the english operating instructions, and the tape transport was jammed due to someone who had obviously pried on it with something like a screwdriver? The Seller appologized and asked me to send the camera back and she would immediately send me another one that she guaranteed would be new. I never heard from her again. He eBay account was closed and now everyone who bought from her in the previous 2 weeks got ripped off.
When I got her address and telephone number from eBay, she had a post office box in a border town in Arizona that was just 2 blocks from the Mexican border and she listed a Mexican telephone number. When I called the telephone number the person who answered did not speack english and I doubt that he know what I was even asking him.
I filed a fraud report with the Post Office (a real waste of time) and both eBay and PayPal ran investigations. I attempted to stop my credit card company from paying the charge to PayPal but they refused saying that PayPal did nothing wrong, and they only acted as a middle man to transfer the money as I directed. The credit card company refused to send me a letter indicating that they refused to remove the charge.
eBay would not pay me from their so-called $200 fraud insurance because I could not get a letter from my credit card company showing they refused to remove the charge from my bill. Also, eBay only gives you about 15 days to handle all of the paperwork and if you don't get them all the paperwork they require by the deadline your claim is denied anyway so it probably impossible for most people to get that kind of documentation to support their claim and get to eBay within their short deadline...And I suspect that they know that and count on that to no have to pay the claims.
