This is a very gray area Djetset. While this design did eventually morph into the A99, after several changes, this actual proposal was for the next-generation of A90. With hindsight we know that there was no such car. This website certainly aims to be more accurate than most, but here we have a problem: When this design was requested by BMC, it was as an A90, when it was drawn at the Pininfarina design offices it was as an A90. As it eventually emerged, with many revisions, it was as an A99.... In my opinion this throws up too many opportunities for pedantry so I feel that 'Westminster' is probably the safest answer in this case, and the one I was hoping for when I set the puzzle, therefore I awarded Wendax the point.
