The best place to get it is dealer. Theres so many options for it. Smallest thing you dont have makes the biggest difference. Like heated steering wheel, controls for radio and the turn signal switch stuff. I took the time to take a pic of my '15 steering angle count in my '11. The count is different then i told you on this one, not sure if its cause its a challenger. Last one i had issues with was a charger. Heres the count pics tho.
