Whats the big deal? it is a used car and not even sold by a Chevy dealership. It is basic supply and demand, if no one comes around and pays it they will lower it. When you sell something don't you try to get the most money you can? When I put something up on eBay, I am not thinking hmmmm what would be a nice fair price for consumers out there. I research how much people will be willing to pay for the item.
