Jay & Dolly,
We have insurance through Hagerty. No deductible, no mileage limit, up to $40,000 collision coverage, and I only pay $625 per year.
I've heard more recently that they won't insure Cobra's unless you've owed it for over a year and have a good driving record. Either way, check it out!

Good Luck,
Todd & Kris
