X5 Auction Prices

[ant1973]

I was wondering if anyone could help me with auction prices for a 57 plate X5 SE 3.0d - not fussed about spec. There are 3-4 poverty spec examples on autotrader for £25 - £26k. I was wondering what they might go for in terms of an auction. Not brave enought to buy one myself but I have a friend who is a trader that is happy to buy it on my behalf.

Thanks in advance.
