I have run the Berlina Register since its inception in 1997, but I also took up the Giulia Register for the US after Dave disappeared from view some years ago. I had one brief correspondence with him some time ago; he said it was fine for me to continue it. I didn't get any of his Register info, which I presume he still has. I got a list of US cars from Barry Edmunds, which was my starting point, and have added to it over the past several years, now totally more than 200 cars in North America. See it and the Berlina list at
www.berlinaregister.com. I need to update both lists with additions, which I'm planning to do this weekend.
I don't know anything about Dave's current status or cars, and haven't had any contact with Gary.
