Those diplomatic plates remind of the time when I worked at a local Cadillac dealer in Santa Monica. The Russian consulate brought their 1995 Fleetwood Brougham in because the doors were falling off the hinges. You'd be surprised at the armor plating the doors had. The windows were 2 inches thick (and they moved up and down!). The best part was they had a 2 1/2 gallon oil tank in the trunk that was pressurized. They could lay down a strip of oil from the spray bar running the length of the rear bumper.
