momma,
Did you check with the insurance company that insures your other vehicles?
State Farm will insure my trucks at a very reasonable rate as long as they are not my primary vehicles and as long as I do not regularly drive them to work. Also, I cannot drive them for any money-making (business) purpose.
Their price is better than Hagerty's but I am pleased with Hagerty and have not changed, yet. Hagerty requires that the vehicle be parked in a locked garage.
By the way, your question and situation is not that unusual: search this forum on the word insurance and you will get many threads that discuss this situation/problem.
