I understand your point, but it seems like these cases are different from your analogy to Sony. You had an isolated incident with them. These occurances with BMW are not isolated. Similarily, Sony is known for reliability. I'm sorry, but when we purchase a BMW we do expect reliability issues to arise, but that is the price to pay for driving pleasure heh. We expect that the warranty we paid for will be honored.

Does this sound isolated?
