IIRC the 6x6 Perenties have the turbo engine, which is the only attraction I can see to one, as I remember seeing a video where Land Rovers were getting stuck in a mud hole, but a 6x6 one just drove straight through.
I think think the 6x6 was owned by the guy who built the futuristic cars based on Landies for a movie like Robocop, Total Recall or some such. Maybe it was The Expendables was there a 6x6 in that?
