Hmmm... I'm thinking maybe I should do that with my marriage certificate. The next owner might really appreciate that.I only have a PDF for the 2015. I had the original for the 2006.
I make a ring binder with them, photos, and other items in there. The next buyer usually likes having these items. I believe it also delivers a non-verbal message that this is a car that was cared about, and well cared for. Every little advantage at negotiation time, please!
