Adam the year book is available through enrico's site. As for the black Ghibli for £6000.00 I don't know it mate.
I have a Ghibli Cup sales "brochure"...
as Pete say's, it is part of the GT pamphlet, but there is a distinct page or two.. Quite small, it's inthe glovebox so I don't have it at the moment...
I could scan it in tomorrow if you like...?
Here is the Ghibli Cup

Looks quite nice, side bolster looks worn in the picture, looks heavily cracked and that wood would have to go or cover it in leather. Does not say how many miles it has done, i would guess around 65k-75k.
