Of course eBay don't know you

They don't know a single member who has ever used the site

And you only have TWO feedback as a seller, so the over 200 does not come into anything when buyers can only ever be given positives 

As for the rest, you would need to ask eBay

And not have any kind of sense of security that there are not some of the biggest scammers to ever have internet on here

eBay is full of scammer buyers

Especially when inexperienced sellers like your self are selling something like a car

Have you fully completed sign up for and been verified for Managed Payments?

If not, you will not be able to sell anything
