You might want to talk to the company that insures your daily drivers...you might be surprised. I may follow my own advice next time around. I'm currently insured through Northwest Insurance under a policy written by Infinity. It's a good policy that offers unlimited mileage in California. They've also been very responsive anytime I've had a question. Here's the contact info.
