It does have a CK, Avid disk, Middleburns etc. So it's a really sweet spec, and if it's only built up in the last couple of weeks, it'll still all be in good condition. Saving you near £400-500.
I'd personally value it at about £800.
My Mod is of a comparative spec, but rear profile, and I'd hope to sell mine for £600-700.
