Per the Order Guide, "Auto Headlamps" are std. on ALL 2011 GT's including base model.
It does seem silly that they tied this feature into the Pony / MCA pkg rather than making it std. on all Premium V6.
But, it may have something to do with the Fog Lamps (std. GT) ... possibly Ford does not have a headlamp switch w/ Auto Lamp but w/o Fogs.
This is my 1st car with this feature. When I've driven other peoples cars with it in the past, I always turned it off as it anoyed me.
