The two models are quite different. If you want to see an Aurion with Lexus badges go to the US Lexus web site and check out the Lexus ES350. It is pretty much an Aurion Presara with some extra goodies like a radar in the front hooked up to an adaptive cruise control and a full glass roof that give the rear seat passengers their own moonroof etc. Unfortunately the ES isn't available in Australia at the moment.
