Calling all legal minds...




Where the car is registered/plated - technically it has to be in the state where the car is "principally garaged". You'll have to decide for yourself whether your SC residency arrangement meets that criteria. And if SC has personal property taxes on autos (NJ does not), the insurance savings might not make it worth it.
The best thing to do might be to call DMV in both states, and just ask them. Tell them you have a seasonal place in SC, and ask if you can drive an SC plated car in NJ with your NJ driver's license. And ask SC if they require an SC driver's license to register a car there.
What if I had homes in 4 states? The cars I kept at each home would have to be registered in that state, since they were principally garaged there. But I myself cannot hold 4 driver's licenses, from 4 states. So right away, its impossible for all your registrations to match your driver's license.
