That Edinburgh one does look nice, though wheels are not great (same as my Winter ones) and even with that low mileage it seems optimistically priced IMHO. There is also a red S8 about to pop up for sale on the A8/S8 Owners page. similar optimistic price and again the wrong wheels, though the red looks stunning. No further details on it available yet though....
