Maybe you saw my previous post about the MacNeillie Discreetly Armoured Range Rover. The short of it is, it's a Classic Range Rover, and it's armored. Best of both worlds. But where there's give, there's take. While it's probably not too hackable, it probably won't protect you from much modern weaponry. They should've made the whole thing into a faraday cage, but 20/20 hindsight.
If you find yourself wanting protection from more advanced threats, don't worry. There's the Range Rover Sentinel, produced by the Special Vehicle Operations division of Land Rover. This baby can hold its own against armor piercing incendiary targets and grenade explosions from all sides. The gas tank is sealed, the tires are run-flat and it has a secret exit incase the doors are blocked. It's loaded with 2 batteries, but that's really not a big deal. There's also a fire suppression system in the cabin and engine compartment.
But to the unsuspecting eye, this looks like your basic Autobiography. It'll run you a little more at $450,000. But you get more than just a car. The price also includes a driving course. Land Rover says it's not offered in the United States, but I'll bet you there are a couple around.
