I have an "agreed to" value on my cars and the premiums are based on that value. I am only trying to say that it really don't matter much what "was" agreed to when you have a claim. Most will try to say......Yeah, we agree that the value of your car was blah, blah, blah, but that was a couple years ago. You drove it 3000 miles since then and now it is only worth blah blah. Years ago I had a 84 Eldorado Barritz with under 10K miles and had it insured for an agreed amount of $12,000.00. When it got stolen, somehow now it was only worth $5500.00. I was not able to sue them or anything. The only option I had was to use an arbitrator. Somewhere I read that Insurance companies own 2/3rds of the wealth of this country. They didn't get that by playing fair. I have that warm and fuzzy feeling knowing that my 68 Charger has an "agreed to value" of 89K. However, like I said, I hope I never have to find out if it is valid. My biggest worry is if it gets stolen or burns up in a fire.
