Insurance Hagerty/Grundy ??

Parking it in outside a restaurant while you go in to eat, or in the parking garage at work = the car is left unattended and not in a locked garage, and that is something they don't cover. If you take it out and cruise and don't leave it unattended, so long as it's less than 2500 miles, and I think you're good. If I couldn't cruise in mine I'd tell that insurer to stuff his policy.
