Here is the GA rundown:
1. The IM had a Certificate of Origin (CO) from IM in Canada; no title. It was registered as a 1958 Porsche 356A Roadster. No title. IM assigned VIN.
2. The Ferrari 250 GTO had an AZ title as a 1962 Ferrari Special Construction and was registered in GA as a 1962 Ferrari. AZ title. AZ assigned VIN.
3. The Jaguar XK120 DHC had a CO from SAS in Knoxville. It was registered as a 1953 Jaguar XK120 in GA. No GA title. SAS assigned VIN.
4. The Bugatti Atlantic had a CA title as a 1937 Bugatti Atlantic Special Construction and was registered in GA as a 1937 Bugatti. CA title. Builder assigned VIN.
5. The SAS Outlaw Coupe came with an SAS CO and is registered in GA as a 1957 Porsche Coupe. No title. SAS assigned VIN.
6. The 1966 Mustang Convertible was registered and retitled in GA as a 1966 Ford Mustang. GA title. Pre-17-digit VIN.
The IM and Jag transferred on the registration to GA and TN respectively. The Bugatti transferred to France on the CA title. The Mustang transferred to GA on the title.
I do not know why you would need a salvage title. What is it registered as now? Look at the clause in the GA law that says a car can be registered in the year it was built or in the year it looks like (SEMA?). All of this has emissions and tax implications.
