When I talked to Hagerty last year, they required the car only be driven to shows and cruise ins and could absolutely not be driven anywhere as a daily driver (work, store, etc.).
That simply isn't true, I drive my car to the store occasionally, I just jump in and go for a cruise with no intended destination etc. I have told my agent that and he said that is perfectly fine.
As far as the store and other things, the key word is occasionally. They do not want it driven as a daily driver, like we would our other cars.
