Perhaps you should look into it, Tony Quin has built four containers in OZ which hold 4 cars each & was offering the first 16 owners to put their hand up free shipping from OZ to NZ, Look I dont know if your SLC etc would even be eligible, but other than possible production #'s I dont see why not, they run an interesting parity system where your grid position decides your minimum pitstop time, eg if your on the front row your pit stop time is 70 seconds, row two is 65 seconds etc, If you got 4 USA cars in one container you might be able to swing a subsidised deal, Can Am cars managed to do it a couple of times so far, Speak to Jay E, he has ties down our way...
