Picked up another car!

What would the differences be on a Dart "Special"?
you know, until I saw that dart, I had no idea there was such a model. I'm pretty sure I've never seen another one. I wish I had taken a picture. I remember it had a block lettering chrome "SPECIAL" on both sides. I can't remember exactly where it was attached. I'm thinking both quarter panels, or maybe C-pillars. I used to drive by the house fairly frequently, and it had not moved from where it was parked in front of the garage for some time.
