Heritage Certificate questions.

I am considering getting a Heritage Certificate for our car, as an xmas gift for my father. Looking through the site...(www.heritage-motor-centre.co.uk) and i notice there are several different types of certificates available. I guess my question is.... Is the Technical specification package worth the xtra price? If so, what Technical specifications are included in the package? and why do i need these? Im thinking i only need the Heritage Cert, but i dont know for sure? Anyone have the Technical spec Package?

I just took a look at the differences. If you are just trying to give a nice xmas present that shows what the original car was built with, you do not need the technical sheet. The technical sheet goes beyond the original sheet with providing information that might help someone get a car through legal paperwork channels with supplementary documents.

I got just the certificate. It is nice and gives lots of info. If you are going to get it by Christmas, you better hurry and order it.
