Remember that the US is it's own market with different regulations and has a complicated history with imports, so no Hilux. Though it does look like the Ranger is externally the same between NZ and US. I'm not counting maybe 1mm as different.
I am somewhat familiar with a Ute since I've seen Subaru Bajas before. Not old enough to see Subaru Brats around or El Caminos.
It does seem like those people are emulating Americans though a lot of those mods are passable without certification, and it's up to a cop to pull over people using bush lights (they probably won't).
My comment wasn't necessarily to talk about model parity across markets - more to highlight the growing trend of people buying large utility vehicles with a tray as a fashion statement (for lack of a better term) than for its utility.
> "a lot of those mods are passable without certification" Not true. Besides the bush lights, any changes in suspension and wheel size require a certification, with a LVVTA cert plate attached to the vehicle.
There is definitely a case of double standards with police enforcement. 'Boy racers' with modified coupes and sedans - typically lowered, with larger wheels - get way police scrutiny compared to utes with obviously illegal modifications like colored lights, and wheels jutting out past the fenders.
