> In California at least, you are required to file for “planned non-operation”, which is inexpensive but not free. Nothing requires you to do that. In theory (sometimes in practice) a NOOP registration makes it easier to re-register it back to street use later. If you have no interest in driving it on the street, no need for any kind of registration or payment. I've had race cars where I've left registration lapse, since I'm not driving them on the street it doesn't matter. I own (in CA) two cars right now for which I haven't paid registration in a very long time, as they are not street cars.
