I saw a very clean (well new) Falcon on the 030 Facebook group go for just over 1000GBP a few months ago. The bastard still had the factory sticker intact, so nobody had stuffed with it, not even a clock patch. It didn't look like it had ever seen sunlight.
I would have bought it but it would have been useless to me as I wouldn't be able to bring myself to break the warranty sticker. eBay is full of pickers and certainly not the best place to buy.
