Benz S600 Guard Capable of Deterring Bullets and RPGs

The Mercedes-Benz S600 Guard is a car designed to keep some of the most important people in the world from harm. No, not inadvertently sliding off the road, or neglecting to pay attention to the brakelights in front (it does that already), rather, the kind of harm that comes from high-velocity assault rifles and rocket-propelled grenades. You know, the nasty, violence kind of harm.
The S600 Guard was built to meet the internationally recognized Ballistics Standards B6/B7 level of protection. To do that, Benz has given the S-Class heavy-duty bulletproof glass and an internal fortress made of armored steel, not to mention all sorts of different measures to ensure that all of the weak areas of the car, such as the seams, sills and joints are impenetrable by pretty much anything. A self-sealing gas tank, oxygen supply, pneumatic window controls (in case of power loss, intercom, and integrated fire extinguisher are all included as standard.
But safety like this comes in discreet forms. Aside from having the advantage of being produced in mass numbers, the Guard model is visually no different from a standard production model, with the exception of its special Michelin PAX runflat tires. But you’d have to have super-zoom vision to be able to spot it from anything more than three feet away.
