Here are a few of my favorites:
Scandinavian Vintage Ferraris
Site creator and Ferrari Historian Kare Pietila of Helsinki, Finland attempts to document ecery pre-1965 Ferrari that has ever touched ground in Sweden, Finland, Denmark, and Norway and does a damn good job of it!
Ferrari 340 America
Bert de Boer's tribute to these marvelous machines.
Vintage Ferrari Restoration:
Tom Yang has been documenting the resotration of his basket-case 330 America on-line for all of us to enjoy for the past couple of years. Also includes an active message board for those working on their own vintage Ferrari restoration projects.
