I use American National (ANAPAC) for my house, and all three cars. My 911 has agreed value as does my El Camino. I am restricted to 7,499 miles per year, and that is not an issue as even on long trips I am usually under that.
I pay 422 per year for full coverage with a 65K agreed valuation. The El Camino is even cheaper to insure as it is less valuable.
Back in 2007 I was in California and a crazy deer decided to try to jump through my windshield. She caved in the hood, smashed the windshield, and headlight rings, fenders and lots of damage. It was derivable, and after driving through LA at rush hour with a smashed windshield, I got to San Diego and got a new windshield installed and drove it home.
The insurance company did not blink. I got several estimates, and I took it to a place that specializes in old air cooled 911s. I told him to make it look like it did before. It was just a ultimate bug hit, rock chip. No rock chips after it was done.
