I did some research before getting my Barracuda insured after I moved to Oregon. Hagerty was recommended by others, and the pricing was well within budget. That said, there are other options out there, such as Heacock. The cheapest deal I found by far was special collector coverage through my standard "street car" insurer, (State Farm), but they would not cover my Barracuda as it is now mostly a race car.
Good luck!
