Mercedes-Benz has made armored vehicles in the past, like the S-Guard 600 limousine.  However, that pales in comparison with their latest armored vehicle.

The Mercedes-Benz G-Wagon LAPV 6.X Armored Vehicle Concept is designed to withstand heavy punishment.  Combine that with a powerful diesel engine and its ability to go all-terrain, and this is one formidable vehicle. The vehicle tops out at 93 mph and has such features as radar jamming, a mobile command system, and automatic tire inflation.

The Mercedes-Benz G-Wagon LAPV 6.X Armored Vehicle is, at the moment, just a concept and not available for purchase.
