I went with American modern Insurance Group. They are about 1/2 the price of hagerty and I heard good reviews and no problem with claims. They also do agreed value.
I had to sentd in photos of the car. There was no issue on the agreed on value that I requested. The site they used to determine what the car was based upon vin number did not code their application well and they thought my car was originally a 6 cyl and they tried to charge me extra for modification but we got it all straight.
