All true.
What is also true is different insurance companies have different rates.
Hagerty seems to be a good company and lots of people use them I just found when shopping for classic car insurance, all other factors the same, Hagerty was usually the highest priced.
I'm a price shopper and when I can find the same coverage for 30-50% less I'll go for it. YMMV.

Nice Camaro!
