Updated as the original process (strike through) doesn't seem to be valid anymore. Replaced with a new procedure which does work!
There is an option to save the data as a PDF file, so you can keep it on file.
This works for both Z3 and Z4 models (and pretty much any UK BMW too!) and all you need is the last 7 digits of your VIN number.
- BMW's VIN decoder seems easiest to use.
- Go to http://www.bmwarchive.org/vin/bmw-vin-decoder.html
- Enter the last seven characters of the VIN, and the Captcha characters.
- That will bring up your Z3's build data.
