Hagerty may have changed, check your policy. I noticed the daily driver portion used to say something about vehicle needs to be newer than 10 years for a daily driver. Now it just says something like reliable vehicle. I also asked Hagerty somewhere if a minor can drive your car and they said they want younger people in the hobby and the 25 year old restriction was lifted. I did a search for "25" in the policy after a quick skim and didn't see it in there. It used to be no driver under 25, but could have your child drive it if you were in the car with them. Maybe it's changed to any licensed driver?
