When choosing an armoured vehicle, it’s important to keep in mind how badly someone wants you dead. This will affect your purchase. If your assassin is an amateur — perhaps some punk with a .38, which fires a 158-grain, round-nose lead bullet at a velocity of 850 feet per second — you’ll probably be just fine in an aftermarket armored sedan or the one offered by Cadillac. In fact, even if your enemy comes at you with a .357 Magnum — a serious weapon capable of spitting metal-ripping charges at up to 1,395 feet per second — you’ll probably escape without a scratch in one of those sedans. But if someone really wants to kill you, you’d better be riding in the 2005 Lincoln Town Car Ballistic Protection Series. The BPS is a rifle-grade armored vehicle, meaning that it can withstand an attack by professional killers wielding 7.62-mm high-powered rifles or even 5.56-mm high-velocity assault rifles, which fire armor-piercing rounds at more than 3,000 feet per second and can take out targets from half a mile away. Oh, the BPS can also deflect shrapnel from roadside bombs, in case you’ve angered someone with a background in demolitions.
