Pretty much the same in NC, but, it may be a little better in NC.

Once you have your 25+ year old vehicle registered and plates are issued to you:
- you must carry your proof of insurance
- there are no annual inspection (no inspections ever again)
- you may display/use an antique plate/plate, depending on the year of manufacture (but, NC does not "register" that plate/plates)
- you must carry the "modern" plates and registration that were issued to you, so that a police officer can go online to see a photo of your registered antique vehicle (and, a photo of you)

That might seem odd, but I do not let that bother me.
