I think you have well overpriced this bike.
£1000 is probably was it owes you over the last past couple of years but it is unfortunately not worth this much today.
A decent carbon Ribble/Planet X bike with Ultegra 6800 comes below £900 and it is brand new with a warranty.
This, IMO, is worth £500 max on here and £650 on a good day on Gumtree.
Without prejudice
