The first bulletproof Popemobile was built following the first assassination attempt on John Paul II in 1981. The British design firm of Ogle crafted the first bulletproof Popemobile on a Range Rover chassis. The Rover took the precedent set in the design of the 230 G and enclosed the cabin, adding bulletproof glass for a visit to the UK. The raised “telephone booth” at the rear raises the car's overall height to 102 inches.
