If you've got bad guys on your tail, then this is the vehicle that you want to be cornered in.
The Mercedes-Benz S600 Guard boasts a V12 engine, and is armoured to a VR9 spec which means that the underbody is entirely covered with plates, while extra tough steel has been incorporated into the cavities between the body structure and the outer skin, with Aramide and PE components providing splinter protection - basically, you won't be able to blast this bad boy apart even if your opponents are packing some serious ballistic muscle. Mercedes goes so far as to say that it "offers protection like a tank".
The windows are heated and polycarbonate coated, so that they match the metal for toughness. If you do get attacked, there's an automatic fire extinguisher system in the boot, a panic alarm system and an emergency fresh air system if they try to smoke you out. Despite its substantial weight, it can still reach a top speed of 130mph. If you fancy it, a 360 degree camera and a night view assistance option can be added on.
One upgrade that doesn't seem to be available is a rocket launcher, which seems a real missed opportunity to us.
Check out the full spec at the Mercedes website, and mull over the possibility that if you need a car like this, then perhaps you've made a few too many enemies in your life.
