Cadillac The Beast

If its good enough for the most powerful man in the world, then it is certainly good enough for you. President Obamas choice of ride, fondly known asThe Beast, was specially commissioned from Cadillac.
The sevenseat, eighttonne, Beast has bunkerlike protection (obviously), however, the armour is so thick each door weighs the same as a Boeing 747 cabin door. It also comes complete with a separate oxygen supply and a totally sealed interior to protect against a gas attack. Oh, and several litres of the CommanderinChiefs blood, too.
