While the first part of your post is correct, Land Rover is being replaced by Mercedes G Wagen because Ford PAG did not submit the Defender to the tender. DMO can not choose or even consider a vehicle that is not submitted by the manufacturer. That is not to say that Defender would have been successful over the G Wagon during a competitive tender selection process.
Pedro: I think you'll find that is an GPS antenna mount, see the sharks fin antenna at each end. The Aussie Mack R series have had their Hendrickson rear suspension replaced by airbags, at least on the un-armoured version.
