I think I've solved the production numbers for the Z4C 3.0si in the US at least.
I started with
this...
Corrected a couple typos, then started a spreadsheet. Also found another 14 in addition.
I could be wrong, but I came up with:
2104 total North American
828 Manual
1276 Automatic
The year by year break down for each is on a sheet in the spreadsheet.
It may not be perfect, as the date for switching to another model year sometimes overlapped in VIN sequence.
I used
http://www.bmwarchive.org/vin/bmw-vin-decoder.html to lookup last 7 VINs.
Here is the spreadsheet, anyone can add info if you would like.
LIST
It is pretty much empty, I looked up only what I had to. (I did look-up up all the Manuals to figure out the number produced like mine. 1 of 2!
)
