Sorry mate, I've rejected the offer of £400 three times now, I've seen worse condition geo's go for £450 so wont be letting it go for less than that and considering this has everything it came with and more I think that's not unreasonable.
As I said before, Im not letting it go for less than £450, If I included postage, (£25 according to royal mails website) it would be the same as selling at £425
