I have 5 cars insured with Hagerty and currently have a claim pending. I don't like to complain but the service I have gotten is terrible. No one returns a call and the people I can get on the phone don't have a clue. The adjuster who finally came out says he doesn't know anything about old cars and the report reflects this. The 2nd adjuster was even more lost. It would seem to me that if you insure classic cars one would have someone that knows a little about old cars.
Bottom Line: No, I would not recommend this to a friend
