Having owned a car previously brought into NJ by the seller, I can't speak to that part, but I can tell you that an antique vehicle is your best choice. It flies under the radar of most NJ vehicle law with respect to inspection (not required) and registration (one-time fee). Considering that NJ is "the land of laws", it amazed me to learn that. I owned the car in NJ from 1992 to 2014 when I moved to PA and am now trying to figure out how to title the car in PA, having put it into storage for two and one-half years, but that's another issue.
