The last Capri?

Hello, I bought a Capri for a friend. That it is one of the last I knew, because it is a 2.0 Super GT. So now it turned out that it is according to the nameplate Bj 11/84, so one of the last since the Capri for Germany 11/84 ran out! How many Capris were probably built in a month, or where can you ask for it many more were built? The chassis number is ES66098
