Back on again.Pricing hhhmmmm

The Auto Noggy blue avant sold for £3,500 on eBay auction recently and if the battered body albeit with a nice interior of the Kreg 80 2.8 quattro Saloon is worth what he wants £2k whats this far more enjoyable/capable manual S6 Avant worth? Pricing doesn't look so silly now that the cam belt has been done. What's it worth fellas?
