I insure my '84 Corvette for about $100 per year via
https://www.americancollectors.com
That includes collision, comprehensive, liability, and even spare parts stored in the same garage. (For some reason, after I bought my NSX 10 years ago, I drove the Corvette very little. :biggrin: But I didn't want to sell it and collector's insurance was a cheap way to hold onto the car yet drive it occasionally.)
It should be under $400 a year for an NSX worth $30k to $40k, but there are lots of restrictions, such as
1. Can't use it to commute to work
2. Must prove have a commuter car & a back-up if that car breaks
3. Must be stored in a locked garage
4. Drive less than 3k mi /year
5. No driving at night
Note that NJ has about the highest auto insurance rates in the US, so you may be able to do better. Just make sure you can live with the restrictions.
I keep my NSX on a regular policy, at $650 per year with full coverage. But that's with a 3-car discount. And, I'm even older than Larry B, so this is one case where age helps.:redface:
