Insuring a 350z at 18 price?

I’m about to be 18 I have a 350z and I don’t drive it much as I’m waiting to turn 18 to get my license. I was wanting to know how much it cost to insure it at a young age. When i do turn 18 I want to make sure I can afford it as I have read it can get a little crazy. An just want to be prepared.
