Final update on getting plate for Roxor. After talking to the dealer in Phoenix, I had an epiphany. Do not go to the AZ MVD office. Find one of the authorized 3rd party offices. Easy to find on the AZ MVD website. After finding the location nearest me, I once again gathered my information and took it to their office. Fortunately, the office was only a couple of miles from my work. I laid out my documents and approximately 10 minutes later I had my plates. Even with the premium charged by this 3rd party office, I saved money. Apparently, the clerk at the MVD office incorrectly calculated the sales tax on the Roxor. So, my individual ordeal is over. I hope that these entries help others avoid the hassle of getting plates for this very cool vehicle. Let me repeat one more time. If you buy a Roxor, have the dealer take care of the registration. If you do it yourself, go to a third party office authorized by the state to register vehicles.
