The registry does define cars into categories. "Original", "Original/Restored", "Original/Rebodied", "Reconstruction", "Air Car" and then the replica's or kits.
"Original/Restored" defined as having less then 50% of it's body or substructure replaced not including the main frame tubing or pieces carrying it's original serial number.
"Original/Rebodied" defined as having more then 50% of it's body or substructure replaced not including the main frame tubing or pieces carrying it's original serial number.
A car rebuilt from a major accident including replacement of main frame but some part of the original chassis remains would be a "Reconstruction". It would also need documentation of the work done.

Some of this brings up some questions for me in regards to CSX2142, a personal favorite car of mine and exactly how it should be classified now. 2142 was rebuilt using some of it's original parts and some parts from COX6010. Exactly how many 2142 parts I don't know or if the majority of those were even from 2142. COX6010's legacy is listed in the registry under COB6010. Not sure if that's a misprint or what happened there either but at least both cars history is known.
