I am sure I stumbled on a website once, where you could actually get a copy from Ford of the original sales receipt that was given to the first owner of the car.
All you needed to supply was the VIN number, and you received a delivery sheet listing all the details such as engine, trim, accessories, colour, where the car was assembled, delivered to, and even the name of the original owner.
Sorry I can't remember where I found it. A bit of digging on Google might unearth something...I think it may even have been the official Ford America site.
