I know the Jota is not the original, as I know the person who built it. It was built from a Miura using the drawings that Bob Wallace used on the original, and using original parts where possible, or very carefully replicated parts where it wasn't. The car has the approval of the factory, to the extent that it was displayed in their reception area during the 40th Anniversary Celebrations in 2003.

So whilst technically you are correct in saying that it is just a 'replica' it's as close to the original as possible.
