Just by knocking the window of a car (thanks TJ for the correction), it is possible to tell if that car is bulletproof or not. This time, I am showing you guys how to do that with a Land Rover SUV that I came to see if my family. We took a look at more than 20 different cars today and after all, we found out that 2 of them were bulletproof cars.
