Thanks for the replies, everyone! I've attached a pic of the Aristo. As you can see, it got scratched on the side and a little on the roof during freight, but I guess that's something that couldn't be helped. Oh well <_< It didn't come with wheels either, so I got very temporary wheels from the junkyard.
It was imported will little hassle through a couple "trade secrets", that I'd rather dicuss in private, but I have no problem sharing. RHD is not illegal at all; you just have to know how to go about handling the paperwork.
In actuality, it's already been proven by a registered importer that the import models are equivalent in safety with the US spec GS300, providing you have airbags. That information can be had online. I'm surprised you were denied a letter from Toyota, though they probably just didn't want to take the time to help you or take responsibilty for anything if you got in a severe accident or something.
If you have any questions about it, call me @ work (310) 219-0250.
