I used to have Farmers insurance until I got in an accident. Even though I had a local insurance agent, because I had to file my claim after hours, I had to contact a generic claims call center. Then, since I initiated the claim using the 1-800 number, I had to complete the rest of the process that way. At that point I was asking myself why I was paying a premium to have a local agent when he was doing nothing to help me. After the whole experience, I decided to shop around and ended up choosing Progressive. They had much better prices and since it no longer mattered to me to have a local agent, I signed up. I've had nothing but a positive experience with Progressive so far.
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.
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.
I have had Progressive for years and have never had any trouble. My car got plowed into by a deer, and Progressive was reasonable to deal with. Their rates are also about the best I can find. We bundle in our home insurance (through some licensed third party) and save even more! Our rates just actually went down this past 6-month period which was a pleasant surprise.
Like regular car insurance, there are several parts with classic and collector car insurance. Some insurers like J.C. Taylor require your classic car be at least 19 years old, while others like Grundy will insure a car of any age. Availability of discounts should also be a consideration, as Safeco gives you a percent off your premium if you bundle your classic car policy with a regular auto policy. Another underrated feature is an inflation guard, which will increase your protection limits as your car appreciates in value. You can see a full list of each company's benefits below.
