If she had not taken the trip to Turkey in the 90's she would still be save-able. I was fortunate to go aboard her when she was anchored off of Istanbul, the interiors were intact apart from furniture. I remember being very impressed by the quality of the carpeting in the main lounge. I have seen pictures of her stripped interiors now, personally think the cost of restoring or re-purposing her is prohibitive. The only slim possibility would be the QE2's current owners, the two ships tied up together would look amazing!
Other than that she would be better put to use as an artificial reef.
