You know the joke about bimmers right? If not, here goes:
What's the difference between a porcupine and a bmw?
With a porcupine, the pricks on the outside.
Now, before any bmw people that might be lurcking these boards want's to flame, relax. It's a joke. I have lot's of friends w/ bmw's. I'm actually good friends w/ a couple...one of which runs the web page, bimmerforums.com. He actually told me the joke.
