FYI - this is a scam - the miles provided are the same as what was included in a 2017 BaT auction, and the seller's description instructs you to contact only via email. Just thought I'd mention this in case anyone was interested in the car (which I presume is not actually for sale)
I reported it to Ebay - we'll see how long it takes them to pull the auction.
