I recently purchased a 67.5 Datsun (my new fairlady) and applied for Hagerty insurance. I mentioned that I would drive it back and forth to work on sunny days, and they denied my application. They told me to re-apply in a year. I am certain that if I said I was only going to shows, they would have been fine with it. It doesnt make a difference if you only drive it 10 miles a year...if that ten miles is to work, you will be denied. They dont actually check an odometer, so there is minimal restrictions otherwise.
