Check into Grundy Collector Car Insurance. I have mine insured for an agreed value of $25,000, full collision, comprehensive, liability, spare parts, towing, under insured/uninsured motorist, etc, etc, etc and it's only $178/year with $500 deductible on the collision and comp. Basically anything that might happen, I'm covered. That being said, I really hope I never have the need to make a claim!
They allow you to (for example) drive it to work ONCE IN A WHILE, go cruising, maybe take it to the store (and park in the farthest away spot) SOMETIMES........................How they would know is a question. I think they somewhat rely on the honesty of the policy holders. Obviously can't be used as a daily driver and the premiums reflect that. No mileage limits either. I can't remember everything right now.
Got to remember, any specialty car insurance isn't for daily drivers. If it was, the premiums would be much higher.
