A tad pricey, but not a bad investment if you are visiting the southern border (or other war zones), or have to transport certain goods or offer certain services in rough neighborhoods, or are a very important person who wants to cruise around in style and needs protection.
This description, of the Lincoln Town Car BPS, is so whack and yet so fascinating: "The defensive modifications that go into the Town Car are extensive. Hidden steel plating and ceramic-aramid plating surround the passenger compartment behind the standard sheetmetal. Since most shots are taken at visible targets, the BPS car's glass is nearly 1.6 inches thick, or 40 millimeters, quite a bit thicker than the 5mm glass in most regular cars. The floor of the car even gets an aramid mat beneath the carpet that offers some security from a grenade attack."
Grenade attack? Man.
