Hi Dom,
You could give
Grundy Worldwide a try. They insure three of my "fun" cars, one of which is an RCR (but that is for comprehensive only since it's not yet finished).
Note that the premium (with Grundy) is based purely on the agreed value of the car, not what kind of car it is. But I do have to prove/agree that:
1. I own other vehicles that are used for daily driving (but nothing I see about where the daily drivers are located).
2. The vehicles are securely stored inside.
3. No family members under 25 are allowed to drive the vehicles.
Based on my policy, the rate works out to around 600-700USD/year per $100,000 value.
One thing about State Farm that other folks may not be aware of (they insure my daily drivers) - if you have an umbrella liability policy with State Farm, they bump up the premium for your umbrella policy significantly for every car you own that is not insured with them. This includes my RCR which is up on jack stands and represents very little liability, unless it falls on a visitor
.
Best Regards,
Al
