I know of 15 in NZ, breakdown is as follows:
White 8
Orange 4
Black 3
Have the VIN's for most of them, but won't be posting those for obvious reasons.
I would say there is closer to 20 all up in NZ, the press car (on TM right now), the 14 BMW NZ initially allocated to the dealers was split fairly evenly between the Auckland 2, Coombes, Jeff Grey, and I'd say Cooke got allocated at least 1, seeing as there was one for sale in Queenstown last month. Can't remember the exact split, that memory has been lost to the sands of time.
