yes you import i have seen 2-3 for sale in japan for NZ$46k then you have compliance, freight, import duty etc... still looking at $50k+ better to buy the one in Christchurch and its also road legal.
i have to say in another 8years the price would be alot more than what they are now as 22b are becoming more rare. In the UK 22B prices are starting to move upwards for excellent examples.
i have 3 friends overseas that have 22Bs and they are kept as collectible investments.
There is a 22B in NZ that has done less than 10k and i have seen 1 for sale ex japan that has only delivery ks. Did you know the sultan even has one.
