If one looks at Gateway's prices, everything is high-dollar and very few sell thru ebay. (same as with many brokers on ebay).
Maybe they are using ebay as advertisement and sell in-person - but many of their cars are relisted *many* times (also true of many brokers on ebay).
Brokers are always highest-priced.
So logically, then, I have a hard time believing they have priced this car (or any car) at what the market is willing to pay.
I saw it first listed perhaps a month ago, and IIRC it was on consignment, and it went non-available at end of 1st auction.
My hunch is the owner wanted $15, they tacked their markup on it, owner saw how high the price went, 'reclaimed' it to sell himself at his $15, and that didn't work either, so now it's back. (again, just my hunch)
