Chuck is a great guy but at some point doesn't the registry become a group thing rather then personal property?
Unlike others, I have not received any kind of a follow up e-mail after attempting to log in.
It's a little foggy but I'd say that was four or five years ago so I have long ago given up or even continued to think about that web site.
The SAAC Registry is probably the largest and most successful of any that I can think of.
It still refuses to go anything other then printed simply for security reasons and yet the Cobra owners broke off and have their own on line Registry. It is very accessible, so they are doable.
There are different approaches to doing them. Shelby American has it's own of current production cars. It is not viewable or in print.
They merely confirm serial numbers as one of their products.
