1LE,
It depends on whether you're talking about a privite sale or Barrett-Jackson. One is triple of the other. To get the lower value, you'd have to produce all the paper work under the sun - for the higher price, all you need is a shinny paint job.
In all seriousness, the way the values are going these days, there's absolutely no way to predict what a car might bring. The hobby doesn't belong to the hobbiests anymore......
