Coming from the UK, you can't always apply the exchange rate against stuff, it's all relative.
If you earn 50k sterling and buy a mark 1 GTI for 25k sterling it's 50% of your yearly income.
If you come to NZ you won't earn 2.65 times your salary from the UK, so if you earn 50k NZD there is no way on earth anyone here would pay 65k NZD it would be more than 100% of your yearly income wouldn't it?
My mates come over and say wow look at that mansion it's only xxx in pounds, but that only works if you have pounds to start with, if your here earning NZD that's what you have to spend aye?
