Insurance adjuster here - I have regular old "full coverage" (comprehensieve, collision, liability) on my 70 fully done car with 250 deductibles - it is very cheap to insure with the company I have been insured with for 15 years. I settle claims on a daily basis - sometimes on antique cars - If there is a total loss or repair question - insurance adjusters are not out to get you - we understand the value of older cars and a lot of us are hobbists too. I know pretty much when I see a car if it is totalled or not or basic value based on my experience - if it is questionable I will run it by the boss and we will send out an independant appraiser who will establish a fair market value - if the customer disagrees he will then hire his own independant appraiser for about 100-150.00 and then the tow independants fight it out - if neither can agree to meet in the middle a third independant appraiser is called in and the cost is split between the insurance company and the customer and that independant appraisal is final - he may say higher or lower or somewhere in the middle. This almost never happens - In VA (I don't know all state laws) we owe fair market value (what you should be able to replace the car for realistically - not what you paid or have put into it) I know I have put more money in my car than it is worth but if mine gets totalled I would expect closer to 20k vs. the 25-30k I have put into it. Those specialty "stated value" or "agreed value" policies have sticky little fine print things stuck in there that may tell you that there is no coverage if you have a loss while driving the car to the grocery store - If you intend to use the car you also have to think about liability for the other fellow you may hit. Bottom line - Insurance companies have to pay the right dollar for the car whether it be a 65 mustang or a 2003 corrolla.
