My cars have always been registered as what they are, in one case a 27 model T and another a 23 model t. I've had the same insurance agent for 25 years, and one day I ran into him when I was driving my 27 and he said "THIS is the model T we registered?" He was thinking nice little stock T all those years. But I still have them registered the same way.........never had a claim though, so who knows.
