Odd... . right before I moved I registered a Jeep Wrangler that I bought out of Florida and it had about 5200 miles on it. I reigstered it at AAA and they were confused about the law and I managed to talk the nice lady into agreeing that the law only applied to vehicles of the currentl model year!
I also bought a new Ducati at ProItalia in Glendale and the bike was a 49 state bike that was shipped to CA by mistake. Registration on that took forever, but somehow the dealership worked some magic. It ended up getting registered after all - don't know how... .

Sorry I realize this doesn't help - but might spark some ideas... . or not.....
