We brought our Jeep Grand Cherokee from the UK to NZ 12 months ago. The value in the UK had plummeted in recent times thanks to the 4x4 school run drivers.
We got a C of C from Chrysler at no cost.
Importing into NZ was no problem, the vehicle has to be spotlessly clean, have a C of C, and to pass the WOF test.
The best for us is that the Jeep is now worth a lot more over here that it would be in the UK. The total cost to get it over, and in, was around 1600 UKP, money well spent we consider to have a vehicle of this quality and which is almost necessary to go to a lot of the out of the way places, and to safely navigate the seemingly endless road works.
