Not sure how well would a RWD Toyota premium sedan would work here, as Toyota Australia also has Lexus with its RWD sedan range (Plus RHD Mark X is JDM-only. Brand new ones sold by Toyota HK still have the 180KM/H speedo.). The Mark X shares the same platform with the Lexus IS/ GS (The Mark X slots in between these two in JDM land.) & Crown, which will make it hard to position down under (Especially the price, it will clash with Lexus here.). I guess the only other way is to get an importer to apply for the car to be added under the SEVS registry, so that it can be brought in as a low volume import (Might take a while though with the 18 month from release window, unless someone starts a petition and show an importer that there is demand for the Mark X in brand new form.). Now, if only the market would open up to parallel imports.
