Neil gave me a list a couple of years ago with:
NZ New (all 16vs):
Red- 7 (Including one tourist delivery)
White - 3 (one since de-registered)
Blue - 1
Black - 2
Imports:
White - 1 ex UK
Red (but not tornado red) ex Sing
Black - 1 ex UK
Purple - 1 ex UK
Green - 1 (VR6) ex UK
Blue - 1 (VR6)
One of the NZ red cars was written off in WLG (last year?)
