BMW promises boredom

BMW is well known for its' luxury cars. It's slogan promises the buyer or driver the experience of Performance, Precision, & Perfection. And rightly so.

But do you know that BMW also promises boredom. Yes, that's true. Just look at this advertisement board.

Take notice of the comma after the word "Goodbye".
Reading it in a grammatically correct way would mean that BMW is promising boredom to its buyer. Hmmm...small error but big difference.

Now, I don't want to buy a BMW because it will make my life really boring.
