BMW's Security Division vehicles are custom-built at the company's headquarters in Munich, and can be ordered for delivery to anywhere in the world, in both left and right-hand-drive form.
"There's an armoured E66 7 Series - the previous generation - in Australia at the moment, brought in for the US Consulate," BMW Production Communications Manager, Tim James, told TMR.
"The new armoured 7 Series - and the X5 version - can be ordered into Australia but only by dealing directly with Munich. They're a very specialised build, and they can be tailored to both left and right hand drive."
