While State Farm's shopping experience is well-reviewed, customers did not feel as strongly about it's claims handling process. The company scored about the same as the other four large companies, but was still mediocre. A large national company may be expected to not be very efficient because of the various departments involved in handling individual claims. If you want the assurances guaranteed to you by a large, "legacy" carrier, then State Farm is the best to go with.
Being in the business for a very long time, I have found that most people are clueless about insurance, even most agents who sell them. I will agree that their rates are cheap. But I wouldn’t recommend them. Inexperienced adjusters. They do not fully investigate. The policy does not cover like, kind, and quality which is bad if you have a new vehicle.
I was with Liberty Mutual for about 15 years and was very satisfied with their prices and service, although I never filed a claim. When I retired and moved from California to Florida, my auto rate went up a ridiculous amount, to almost $10,000 a year even though I had no accidents and one minor moving violation in the last ten years. On top of that, Liberty Mutual screwed up my umbrella policy and told me it was “unenforceable,” whatever that means, but I had to pay for the policy anyway up to the time I canceled and switched to Progressive, which cost about one third the cost of Liberty Mutual for an identical policy. Even good companies change over time.
If your classic car is currenty undergoing restoration, and want to make sure nothing happens to it, Hagerty is the company to turn to. There are only two companies of the ones we explored that have restoration coverage. Since Hagerty offers coverage for a wide range of vehicles, as well as higher than normal spare parts coverage it makes it the superior option for those restoring a car.
