Ebay impulse buy now seller wants out

So as usual I am browsing around Craiglist, Ebay ect. again last night. I see a solid looking 1963 Caddy Deville sedan on there for $1700 and figure what the heck and put an offer in. Well I get up this morning and I won it for $1750. I already found a replacement lower bumper end.

Now the owner has asked me to cancel my purchase without giving a reason. I assume the reason is they didn't pay for the reserve and they didn't figure it could go so cheap. I reached out to the seller and there has been no response. I honestly don't really even want the car very much. My wife already has a 1967 Deville convertible. Just looking for input on what you would do. I am going to sit on it for a day or so. Here's a picture.

Dude thats bad looking, idm drive that car.
