My maths may be wring but take off the VAT before seeing if it is as much as a rip off as it seems. So with the VAT removed that's £1,160. The other way to look at it is that second hand a thing can be worth only 50% of the new price. So that's £725. Either or either was the RFD will, I assume, need to stand by the item when he sells it on. He'll usually put a 50% mark up on what he pays the seller. So that is £400 plus 50% = £600 window price. That way he at least has a reasonable chance to find a buyer. But the only true value of a thing's worth is open market of willing buyer and willing seller. So there's always the auction houses.
