In a spy report yesterday we posted the picture below, commenting on the '58 Ford on the right hand side of the photo.
Thanks to 'Mourning Becomes Electra' and Markus from Bondklub Deutschland (BKD)" we've managed to confirm that the car will be featured in Cuban scenes in Die Another Day. 'Mourning Becomes Electra' managed to find this photo of the car, with Pierce Brosnan during filming in Spain, at http://pro.corbis.com.
So there you have it! Thanks to both 'Mourning Becomes Electra' and Markus for their help!
