It seems to me that ebay prices are typically about two-thirds of market price, or three-fourths at best. Any "sight unseen" marketplace for cars is not going to have very high prices. Most cars running through ebay don't come anywhere close to the reserve. It seems to me like it's a marketplace designed for the sale of junk, and that's a lot of what it gets. I don't consider it a accurate indicator of the true market.
