As Mike P. suggested in another thread, take a look at ebay, both current listings and completed listings. It will give you an idea of what the marketplace thinks the value is. The good thing about ebay is that it reflects SELLING prices, not ASKING prices. You can check Traderonline.com, and Carsonline.com for asking prices and then SWAG what actual selling prices might be. And Mike's words of wisdom certainly apply........................sellers almost always over estimate the level of condition in their descriptions.
