Because I have one on overnight test drive and really like it.
We don't get a lot of choice in this type of 7 seater/this price. It's the only one with a boot you can put anything in for a start. The NZ model has a 2.4 litre petrol engine (we like our engines BIG here) so I think the power worries I've read about on UK sites won't be an issue.
I think our version is different in other ways too- but there must be some stuff that's the same that owners can enthuse about.
