I have two tri fives that are titled and licensed in California. They are both running vehicles. Every year, I just send in my check to California DMV, and they renew my license tags. Are the registration requirements in Arizona just as "easy?" Does anyone know if Arizona exempts these cars from smog checks? When I bring them over and register them, will I run into any problems with smog or any other requirements. I"m just trying to figure out if I have any problems ahead of me if we move. Thanks.
