Hi,
It could of been an option, not sure.
If the question is - does this make it a directors car? Then no its not a definitive answer.
I do have though all the paperwork from delivery, pdi, first registration, first tax and all the subsequent history leading up to my ownership.
It also has all the car phone still fitted complete with power/comms pack under the front passenger seat.
I was at a show a few years ago and a chap started telling me about his car, pretty much the same tail as mine, turns out his was one digit after mine and from the same ford office.
