Sounds a bit like my Kuro that I sold recently. It was a 53 plate with 32k miles and it had to go for £19k. I had it in the the autotrader for £19850 and didnt get one phone call. However it was on PistonHeads and had loads of interest from there. I agree with some of the previous comments that you may need to sell at about 14k to attract people to ignore the mileage.
