The key to any insurance policy for vintage cars is the notion of "agreed value" versus "stated value" as well as any driving restrictions that the policy may contain. Agreed value is the value that the owner and the insurance company agree on as to the total value of the car...most of the vintage car insurers are very reasonable in arriving at that value and, for the most part, will recognize some, if not all, of the cost of the restoration of the car which is almost always more than market value. Stated value is the value that you tell the insurer when you take out the policy. It has little or no bearing on the actual maximum payout you might receive in case of a claim....that will be up to the insurance company as well as where you get any damage repaired. State Farm as an example, has their own claim centers who likely have zero experience in estimating the cost of the claim for classic cars. Also, it is common for the main stream insurers to have a driving limit of some kind in their policies...either an annual mileage limit or restricting the driving to events or parades....that is often lost in the fine print of the policy and can obviously be a big problem if you file a claim where you are out of compliance with that provision. State Farm is certainly a reputable insurance company for conventional vehicles but unless they have agreed value policies I would look elsewhere. Some of the more common classic auto insurers are Hagerty, Grundy, and Heacock...there are also others. I am most familiar with Grundy as that is what I have...my cars are all insured for agreed value and have no driving restrictions. Grundy and Hagerty (and possibly others) will also insure your conventional vehicles and their "fleet discount" rates can be very attractive. One other thing to note is that just because one of them is less expensive in one area of the country doesn't mean that they will have the best price in another area...for whatever reason the price differentials are not consistent...not only for geographical areas but also for types of cars. I'd suggest getting two or 3 quotes. You'll find that vintage car insurance rates are generally much cheaper than policies for conventional vehicles....the risk is lower as we tend to be more careful with our classics.
