I've had Hagerty for over 20 years, but that is changing very soon. I've only had two claims with them during that time (both for cracked windshields) and they were handled very well, no complaints on that end. Over the last several years though (long after my second claim) I've watched the rates steadily go up. It's my understanding that the family sold the company to another insurance company and that is when the rates started to go up. I do know that there is a different company running Hagerty now than who was running it when I first got their coverage.
American Classic's rates were about 2/3rds of Hagerty's rates for the same coverage. Since I have all my other vehicles, RV, and my home insured with State Farm I checked with them and found that they also have classic car insurance. Their rates for me were just a little over 1/3rd of Hagerty's rates! The only difference in coverage is a $250 deductible for comprehensive, everything else is $0 deductibles. Usage restraints are the same as Hagerty also. Considering what restoration parts are costing for these cars now, I can easily live with that $250 deductible. I have had State Farm insurance for years and have had claims, one being a new roof on my RV costing over $7000, and I've never had a problem with them covering the claims. I'm done with Hagerty.
