I believe in this case provenance is like beauty and is in the eye of the beholder . Because there is some family involved revealing what I view as provenance would/could impact individuals security and privacy. The price of the car is not based on in my view /definition of provenance. I only mentioned provenance it in relation to a prior posts that I would describe as argumentative that someone (administration I am guessing) has since removed. When /if the car is sold the information I am referencing to would be transmitted.
