I'm good GR thank you, you ?
I am not sure but the Autobiography means it was made to a customised spec for the original owner but I am not even sure they offered that in the early years but possible. It would only effect things like trim, leather colour, wood colour and the like, i don't think there was much difference to the outside. maybe things like TV screens in the rear and the harmon kardon sound system would be classed as autobiography. i only know of the vogue and HSE with the vogue having all the tricks like heated seats and TV in the front and then there are optional extras you could add but I am not sure those extras constitutes calling it an Autobiography. I imagine there would be Autobiography stated somewhere on the paper work.
Above all i would be very cautious as GR pointed out, these vehicles come with enough problems even when everything is open and honest, no V5 and the confusion over the S/C and spec would have me really concerned. there are hundreds for sale, i bought the first one I saw that ticked all the boxes i knew about, have a search on here, there are dozens of boxes you don't even think of that need ticking
