BMW production data. [UPDATE 09/16: NA market *28i, *35i, E89 Z4; All markets M*35i]
If you want to know how many cars were built in your color/upholstery combination or how many were built with or without a particular option, post your VIN(last 7 characters) and I'll reply to you with your data.
At this point I can provide data for all BMWs that were introduced in the North America after 1983 up to models that have finished production (for example, pre-facelit F10 data is available, but no LCI data since it's still in production). For other markets I got data for all M cars, again from 1983 to the end of production, and a handful of other regular models.
