I don't know if there has been anything published as far as individual states and their legislation on classics. We do not have any problems in Michigan,but these are a big part of our local economies. There are currently three ways to plate your antique car in our state. One is just a normal everyday driver plate. One is an "authentic" plate that is the year of the car(a 1965 Michigan plate stays on your 1965 car as long as you own it). The other is a "historical" plate which is renewable on any vehicle over 25 years old. I am not aware of any municipalities limiting driving on classics in Michigan,but we are limited to shows,cruises,events,when registering as "authentic" or "historical". Your post would explain why I am getting "weird" questions about a car that I am selling. Apparently it is not easy to register these cars in certain areas. I still live out in "the sticks" so I am not aware of many states titling/registering procedures.
