I’m new to this site, recently purchased a 1964.5 K code convertible at a Mecum auction (ridiculous amount). The car is currently in the registry. I think having a registry is a great idea, maybe start with the 1500+ currently in the registry, and start a separate “Verified Registry”. This way people can still self register. But If you want to purchase or sell a car, it would be a bonus to a seller or insurance to a buyer to have it “Verified”. Just my 2 cents.
Lastly, I just purchased a Fourth Addition, The 289 High Performance Mustang, book off of EBay ($50 plus shipping) this week. They pop up every once in a while.
Thanks, Mike
