Whatever we decide we should at least place a comment on the 4 pages as to why the origin is either UK or D. That way future users will know why they differ or are listed the same as their Vauxhall/Opel counterparts.

@antp do you have any preference? I am fine fixing the 3 Vauxhall and 1 Opel we have listed to match whatever we decide then place a comment on each page.
