I am a 2013 ST owner. I purchased my car on Sept 1. I have been posting my impressiojs and pictures at "http://fordstnation.com/my-st/1578-my-st-pure-emotion.html".
Recently, following this forum I have been made aware of the paint chipping that shows up around driver side tail light area. After reviewing my car, I too found out that my ST has similar problem. I posted some pictures and my observations/comments at "http://fordstnation.com/focus-st-repair-shop-service/1858-rear-tail-lights-chipping-paint-4.html".
