Well, the only receipts that an individual can provide would be receipts for parts purchases. There is no way for an individual to prove that those parts were actually installed into the vehicle in question.Yes. They would ask for receipts that would show the owner did exactly what the owner’s manual said to do.
I guess I was not aware that I’ve been in mortal danger of warranty violation all these years because a licensed mechanic (whatever that means) didn’t do any of my oil changes nor virtually any of the repairs on my vehicles.
Any of us could make a maintenance log tomorrow indicating that oil services were done at the proper intervals, but between the log and the receipts, it really doesn't prove that the work was actually done.
