It looks absolutely stunning and caught my eye (not least because I have the same colour XJ6) as I'm looking for a 2nd Jaguar, but then I saw your price......ouch!
Despite the condition & mileage I think you're aiming a little high, but it's just my opinion. From experience I know full well how much it hurts to let something go for less than you think it's worth. Whilst the mileage of this one is higher, it's perhaps nearer the £ mark?

That aside, I wish you the very best with the sale 😊
