If you are not concerned about the cost to repair the car, then insure it as a regular car.
I have some unconventional thoughts and practices involving insurance, mainly centering around "self insuring" against damage to my property rather than paying full coverage on anything (even new cars).
Instead I choose to put the difference in premium cost into a general "rainy day" account and then if the need arises, use that for any repair or replacement. that allows the money to stay mine instead of the insurance company's and allows it to be used for any vehicle and/or other emergency situation. (Sometimes even paying cash for a new or more likely 2 year old vehicle.)
With all that said, my 73 Satellite is the cheapest vehicle to insure that I own.
About 1/2 the cost of my 2000 Dakota and much less than my 2015 Renegade.
