A lot of it is location, but the clarity of the listing and the sellers feedback as a huge factor in how much someone is willing to pay. Both of those cars looked like the needed a lot of work, the one that you referred to as a basket case had a LOT longer description, with a ton of pictures, and as a buyer it looks like the seller isnt trying to hide anything. It also depends on how many people are interested, if people start getting into a bid-war than you will see the price raise substantially, however if there is only one buyer interested, than the item wont see much action and the price will reflect it.
