I expect it's gonna really depend on your agent... Just call around.

I got an agreed value policy for my old Jaguar through my Allstate agent.. he asked me what I thought it was worth, I told him, he said ok and wrote a policy...

Old cars are (A) cheaper to fix than new cars, and (B) not worth as much as new cars.

I expect the main thing that insurers are on the lookout for is folks who want to over-insure their car... if that's you, good luck.

But if you can demonstrate that your car is really worth what you claim it to be worth (receipts receipts receipts), you'll find someone that will write you a policy.
