The Queen allegedly owned the second-most expensive car in the world. She had a massive collection of vehicles but one stood out. This was her Bentley State Limousine, a gigantic burgundy beast of a car. However, it had many additional features that ensured her protection.
This bespoke vehicle had kevlar tires and armor-plated doors. Meanwhile, it could resist chemical attacks as well as significant explosions. There are likely more unspecified features including blood supplies to protect the Queen’s health in a crisis (via Obul).
