Great question and I have done some research on this, yes 25 years or older you can register in the states (probably not California and other super blue states) and I have another option if that doesn't work (vermont)
I have been wanting to ship my Land Cruiser safari vehicle from kenya to USA and have spoken with shippers and brokers, the only reason I have not pulled the trigger is that I dont trust once I release the vehicle in Mombasa it dissapearing before getting on the boat and I will have NO recourse. I have come very close a few times but always chicken out in the end.
I have been succesful shipping items including vehicles from the states to Africa (mainly through Malawi) but scared to try the other way. If I can find a reliable way to get them on the boat and over here I will ship Land Rovers and Land Cruisers, old minis, VW buses, FJ45's all day long!!!!
