Like I said, WHO you trying to fool? Well that would be the DMV in Idaho.
While I don't condone it I sure can understand it! Until just a few years ago there was NO legal way to drive a replica in Hawaii. We found various ways around the law, none of them pretty, but we did what we felt compelled to do. We finally got a law passed allowing us to be legal. Those States that have no provision for making a replica legal should get a bill sponsored and passed into law. Until then, yeah, you gotta do what you gotta do!
If your doing it just to avoid paying just taxes owed, theres perjury laws against that and some have paid a very steep price, including jail.
If your doing because it's simply 'cool' to see that on the title, the question remains: WHO you trying to fool and for what reason? I don't want or expect an answer, it's a very personal question for each of us.
