I looked into this extensively and ultimately decided it wasn't worth it for me. I also live in GA where there was a string of busts some years ago. I've also spoken to local car enthusiasts on their perspective, and the subtext from one who once registered cars in MT was: "I wouldn't do it if I were you", in an ominous way. The discussion suggested he knew something.

But, I see MT plates from time to time, but as c1pher mentioned, I think it's a matter of time before states get hip to this. Further, I don't have time to deal with the state coming after me for unpaid taxes or my wife. She deals with the parade of cars at the house (and stored elsewhere) because it doesn't really concern her. That dynamic changes if we have a large tax bill as a result of a tax dodge. I understand this is my problem and likely not yours. Anyhow, YMMV.
