The first truck I bought in spring of 2015 was a trade from a fleet. The dealership had a folder with receipts and maintenance logs of everything that had ever been done to that truck. That was a nice addition to have. That's what I have on the new truck I bought in winter of 2015. I have a spreadsheet that logs everything, right down to a blinker bulb, that's every been done to this truck with the corresponding receipts.
