I buy and sell a lot of cars..........mainly daily drives, but I have also flipped many specialty automobiles
99.5% of the time the ONLY reason a car is listed for sale nationally on a site such as Ebay is *****because it doesn't sell locally*****
There are various reasons a car doesn't sell locally, including but not limited to the top 2 reasons: >car is over priced<, there is something wrong w/ the car not disclosed from the seller.
Frankly, I have heard every excuse, and every justicication in the world for a car being over priced. Some seller/owners are just weird, some live in an alternate universe and have no idea of a fair selling price...instead they have an "advertised price" and have no value for thier own time, or anyone else's.
In the .05% of the time a used car actually has a legtimate reason for being listed for sale nationally, on a collector or specialty car sight and/or Ebay is because...its a speacialty car w/ a small audience of buyers. Classic Bronco's, muscle cars, street rods, very expensive & exotic cars, ect....belong on specialty sites.
I make a living "avoiding problems" when buying and selling cars. Obviously I can't type out all of my experiences, my best advice is, 1) be a knowledgeable seller/buyer, 2) be fair and conduct yourself w/ high personal integrity 3) always trust your own personal knowldge (gut instinct) and never, NEVER become emtionally attached to a car that would/could alter prudent investment stradegy...be able to "walk away" from any & all deals that are, at minimum at least "fair", but perferably in your favor.<- Period.
