At the end of the film the army truck is chasing Madison and CO through New York. The BMW has its sun-roof open when it passes the yellow cab which is parked up in a narrow alley and blocks the Army truck .(as the truck is too wide, this is where the soldier gets out and asks the cabbie to move, but the cabbie says he is waiting for a fare)

As the BMW speeds off in the next shot the

sun-roof is closed.!
