At the rate sapphires are still getting broken they will be the rarest of all cosworths I think. Really good cars get broke up and despite breakers saying the shells live on, they rarely do. Central day was a good example, not many there in comparison to other fords. Iv always said that if I ever sold mine, which I have no plans too, will only sell to someone who will use it and not break.
Out of curiosity how many are left on the data base now?
