Seeing how cheap they're these days, both 4th and 5th gen - you get a lot of a car for the money. 5th gen are more squarish inside and you get way more room/headroom especially for the rear passengers.
Aim for a S Pack (Spec B for NZ new ones). Jap spec sheets are all over the place - leather is rare, so are sunroofs. Cruise/steering wheel controls, comfort access, Mcintosh sounds ok but unless it is a nz new one everything will be in japanese. NZ navigation is outdated and useless.
NZ new Spec B have majority of that ticked off but lack alloy control arms and folding mirrors. Also 2.5 vs 2.0.
I had 2.5GT, central Auckland + motorway would consume around 12-13l per 100km, round about the same or even slightly better than the 3.0 I had prior to that.
S Package is what used to be called SpecB i.e bodykit, Bilstein, blacked out headlights.
In actual fact, NZ new 5th gen were still marketed and registered as Spec B. Much better specs than an average JDM S Pack with full leather, McIntosh with steering controls, cruise control, sunroof, comfort access etc. BUT no alloy control arms or electric folding mirrors.
They appear to be the same ones as I had on mine (Crystal Eye), probably come from the same factory. Build quality is very decent and certainly look different.
How heave are they? Get the seller to package them up and book a courier to collect through TradeMe. I just shipped a set of stock 18s for slightly over $70 (split into two consignments).
