So if I have a vehicle worth $50k, and I want to ensure I get as close to that $50k out of it that I can, like if a rock falls out of space onto it (comp) or a monster truck runs over it (collision), an agreed value policy seems to be the best way to do so. However, to substantiate the fact it's actually worth the $50k I say it is, what's the best way to get that in writing? Receipts? An appraisal (from the insurance company or one I've hired)? Does it have to be appraised by more than one guy, or do they have to have some kind of certification or something? What about insurance while the vehicle is under construction? Is it better to get comp on the car and write-in the parts, or to get "under construction" insurance? How do you back up the value of a pile of parts - the same way as above (receipts or appraisal)? Many thanks for your participation in this forum - it's opened my eyes even more about insurance! Ever since finding out homeowner's insurance covers nothing with an engine, or parts, etc after a flood a few years back, I've been a little paranoid about keeping my stuff covered. That pile in the garage is worth more monetarily and personally to me than all the other stuff in my house, and to think it's not covered at all gives me the willies! ~Jason
