Lexus engineers have a way of testing to see if their cars are
air-tight.
They would put a cat in the car and close it up. They would check the car
again in 24 hours. If the cat was dead, it passed the test.

Chrysler heard about this and decided to try it. They put a cat in one of
their cars and closed it up. When they checked it again in 24 hours, the
cat was gone....
