An insurer who doesn't understand what they are insuring, should be avoided like the plague.
I spoke to a Progressive auto agent last fall after being told they issue "agreed value" coverage. Nice guy, nice long chat, and it turns out they will SELL you "agreed value" but the fine print says they will pay "Agreed value OR...." and if you've agreed to a value that is less than what they call market
price? You get the short end of the stick, after paying the premium based on the higher agreed value. Needless to say they didn't get my business.
If they don't understand what "agreed value" is, and they don't understand what a documented vessel means...Maybe they are best left to their primary market: Ordinary cars. (Although, their injured-in-the-crash pet
medical coverage is a nice perq.<G>)
