its no secret that the land cruiser prado (in other markets) is the lexus GX in america with minor sheetmetal tweaking:
toyota long ago split apart the ranges in terms of badge engineering. no longer are lexi (plural of lexus) just toyotas with big L's on the back. the 4runner will get a distinctive body for the US and maybe other markets where it will be sold as the hilux surf. it will however, most likely NOT be identical to the prado.
