Once, well - every now and again you run into an advert that makes the hairs on the back of the neck stand up.  Eminem, and I don't mean chocolates.  Like a trailer for a movie you want to queue up for.  It's for a mid-range Chrysler.  The story takes you from somewhere familiar (it must be NYC?) to somewhere you realise you don't know.  Detroit.  

"It's the hottest fires that make the hardest steel."

The ad is so good it feels like it should be for something more amazing.  Maybe that is the point?  Enjoy.
