It is a 805th car made.
There were 4 cars made on 2000-06-19
The rarest option on your car is the option 502. It was installed on 255 out of 821 cars.
There were 35 1998-2000 BMW Z3 M Coupe (CM92) - RHD painted in Cosmos Black Metallic (303) with Black Nappa Leather (Q6SW) interior.
So the details are there somewhere, just need to find out someone who has access to it.
Hope this helps.
