Jim, there were three. As stated earlier by Thorin, serial numbers 0002 and 0003 were rebuilt as "standard" GT40's and the chassis renumbered accordingly. 0001 is the sole survivor, but what a beautiful survivor she is. I don't know why I cannot post the pictures I have, but if somebody wants to try posting them I will be happy to send them by e-mail, as I am in agreement that the Mirage is the most stunning variant of the GT40, and the more pictures that get put up of it the better.
