I don't plan on selling my car unless I really had to, but since I do the work myself and think I do very detailed work on my car and don't have the "Ferrari stamp" of approval, what would be the best way to document all the service work that I did? If you were a potential buyer of my car would you say that the car wasn't worth as much since it wasn't done by an "authorized Ferrari" dealer? (By the way if someone tried to pull that card on me...I would f-you and go away!..LOL!) Just curious of what the opinions are out there. How should I document and make my service history legit? Would you buy my 512TR over someone else's TR that had the same mileage knowing what was done to my car? WOuld it bother you not having the stamp?
