Couple of comments... I write date and hours on all tractor filters, and our autos have "baby books" (wife's term) in them that notes fuel and all maintenance... date and miles. Now, insurance seems to be a necessary evil. We just had our house and barn's roofs replaced, thanks to a massive hail storm last summer. They were willing to replace the shop's metal roof, as well, but that is a Morton Building, the dents didn't really bother me, and I figured the metal roofing wouldn't be a good as the Morton, so we passed. The bill was about $28,000 total. Very high, but insurance was paying, and their adjuster had put it all together. When all was said and done, I asked the contractor what it would have cost, had we been paying out of pocket. His quick reply was "about $12,000". Contractors must absolutely love insurance jobs!
A side note: after the hail storm, there were locally lots of tent cities where paintless dent removal crews were set up to deal with the literally thousands of dinged autos and trucks in the area- seems they travel around the country, chasing storms, so to speak. One of our cars was included- 79 dents, all nicely smoothed over.
