Ok first off..
...do a search under problems, you'll find plenty of stuff [discussion] come up,
.. do a search on Buyers tips I answered most of my own original ?s I had on the JDM version of the VX that have been imported in to Australia [<20]..but there are differences
... as a past owner of 2 SVX, one of which the gearbox had to be replaced...the TOD gearbox, 4WD system seems much less of an issue..this was certainly in the back of my mind as the SVX box rebuild cost me ~$2.5K US to sort, altho TOD on the JDM model enables rwd as an option, whereas TOD US version stays in 4wd...but looking at the tire/wheel combos that several of the US folks run, TOD appears to handle things fine...heat was a major issue with the SVX, do a search on "coolers' here to see what the serious off roaders have done..similarly with some who've fitted Superchargers, to see how TOD handled it...
...SVX ..dirty window guides causing glass to scratch... , VX has some issues with the tracks/guides alignment causing binding..fixable 'do the search' following all the tips I've sorted my Vx window..
...engine life ..for the 3.5L, search again, I'll you'll find plenty there..biggest thing check your oil reguarly ..like every fuel fill up..there's heaps on this, I'll let the experts here speak thru their threads.
...fuel efficiency [remember its 3.5L V6] , body parts/panel availblility [for new], in the US some Isuzu servicing /support an issue has been discussed
...but hey ...lots of eye appeal, looks like its an 05 model even tho they started in Japan in 97,good performance, drives better than most 4wds, excellent 4wd credentials, recaros [and leather in US], climate control, poor rear visibilty [but fixable with rear camera, but side mirrors are a good size/heated], limited production run...
...pick a topic [on things you want to know more on or suspect and search away]

Good Luck
