Man, you PNWX guys are really gettting cozy with NNA! First you get to see some '05 Xterra concept mules, now this.
That head-on shot (#3) really makes those gossamer mirrors look like crap. The chrome has GOT to go, they should be black, not even body-color (or smaller).
Looks like there's no real chance of stepping down to smaller wheels, that spindle won't really allow more than perhaps 1" smaller with a bit less backspacing. Looks like that CV boot has come off the back of the spindle too

Yeah, no biggie on a prototype, but I hope they noticed it.
